Notes:

1.   ACCOUNTING POLICIES

     The consolidated interim condensed financial statements have been prepared
     in accordance with International Accounting Standard ("IAS') 34 "Interim
     Financial Reporting". The accounting policies and methods of computation
     used in the preparation of the consolidated interim condensed financial
     statements are consistent with those used in the preparation of the
     financial statements for the year ended December 31, 2005 except for the
     ones modified by the Company as a result of the adoption of the new or
     revised International Financial Reporting Standards ('IFRS").

     In 2006, the Group adopted the following new standards, amendments to
     standards and interpretations which are relevant to its operations and
     mandatory for financial year ending December 31, 2006. The adoption of
     these new and revised IFRS did not result in substantial changes to the
     Group's accounting policies. In summary:

     -   International Financial Reporting Interpretations Committee ("IFRIC')
         Interpretation 4, Determining whether an Arrangement contains a Lease,
         effective for annual periods beginning on or after January 1, 2006.

     -   IFRIC Interpretation 8, Scope of IFRS 2, effective for annual periods
         beginning on or after May 1, 2006.

     -   IAS 39 and IFRS 4 (Amendments), Financial Guarantee Contracts,
         effective for annual periods beginning on or after January 1, 2006.

     The consolidated interim condensed financial statements presented herein
     should be read in conjunction with the consolidated financial statements
     and notes thereto included in the annual report of the Group for the year
     ended December 31, 2005. The consolidated interim condensed financial
     statements as of June 30, 2006 and for the six-month periods ended June 30,
     2006 and June 30, 2005 included herein are unaudited but reflect, in the
     opinion of the Board of Directors, all adjustments (which include only
     normal recurring adjustments) necessary to properly prepare the
     consolidated interim condensed financial statements, in all material
     respects, in accordance with IAS 34. The results of operations for the six
     months ended June 30, 2006 are not necessarily indicative of the results of
     operations expected for the year ending December 31, 2006.

     Costs that incur unevenly during the financial year are anticipated or
     deferred in these interim financial statements only if it would be also
     appropriate to anticipate or defer such costs at the end of the financial
     year.

     Income tax expense is recognised based on the best estimate of the weighted
     average annual income tax rate expected for the full financial year. The
     estimated average annual tax rate used for the six months ended June 30,
     2006 is 26% (six months ended June 30, 2005: 28%).

     In August 2005 the shareholders of the Company approved the acquisition and
     transfer agreements relating to the Company's acquisition of a 50%
     ownership interest in (CHINESE CHARACTERS) (CNPC Exploration and
     Development Company Limited ('CNPC E&D')). CNPC E&D was formed in 2005 and
     was wholly owned by China National Oil and Gas Exploration and Development
     Corporation ("CNODC', wholly owned by China National Petroleum Corporation
     ("CNPC')) and one of its subsidiaries. Under the terms of the related
     agreements, CNODC transferred certain oil and gas exploration operations
     into CNPC E&D and the Company contributed to CNPC E&D its wholly-owned
     subsidiary, PetroChina International Limited ('PTRI'), and cash amounting
     to approximately RMB20,162 million, which is the difference between the
     cash contribution of RMB20,741 million payable by the Company according to
     the acquisition agreement and cash consideration of RMB579


                                        4



     million for PTRI receivable by the Company. The terms of the agreements
     grant the Company the right to appoint four of the seven directors of CNPC
     E&D and enable the Company to maintain effective control over CNPC E&D.

     The investment in CNPC E&D and related transactions have been accounted for
     in a manner similar to uniting of interests as all entities involved are
     under common control by CNPC. The consolidated financial statements of the
     Company have been restated as if the operations of the Company and CNPC E&D
     have always been combined. The payment was made directly to CNPC E&D,
     therefore the difference between RMB20,162 million paid and the net assets
     of RMB35,551 million at the effective date acquired (including RMB20,162
     million contributed by the Company and RMB50 million for the contributed
     paid-in capital by CNODC and its subsidiary) has been adjusted against
     equity.

     The summarised results of operations for the separate entities and on a
     consolidated basis for the six months ended June 30, 2005, are set out
     below:

2.   CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS

     Estimates and judgments are continually evaluated and are based on
     historical experience and other factors, including expectations of future
     events that are believed to be reasonable under the circumstances. The
     matters described below are considered to be the most critical in
     understanding the judgments that are involved in preparing the Group's
     financial statements:

     (a)  Estimation of oil and natural gas reserve

          Oil and gas reserves are key elements in the Group's investment
          decision-making process. They are also an important element in testing
          for impairment. Changes in proved oil and natural gas reserves,
          particularly proved developed reserves, will affect unit-of-production
          depreciation charges to income. Proved reserve estimates are subject
          to revision, either upward or downward, based on new information, such
          as from development drilling and production activities or from changes
          in economic factors, including product prices, contract terms or
          development plans. In general, changes in the technical maturity of
          oil and gas reserves resulting from new information becoming available
          from development and production activities have tended to be the most
          significant causes of annual revisions. Changes to the Group's
          estimates of proved reserves, particularly proved developed reserves,
          affect the amount of depreciation, depletion and amortisation recorded
          in the Group's financial statements for property, plant and equipment


                                        5



          related to oil and gas production activities. A reduction in proved
          developed reserves will increase depreciation, depletion and
          amortisation charges (assuming constant production) and reduce net
          income.

     (b)  Estimated impairment of property, plant and equipment

          Property, plant and equipment, including oil and gas properties are
          reviewed for possible impairment when events or changes in
          circumstances indicate that the carrying amount may not be
          recoverable. Determination as to whether and how much an asset is
          impaired involves significant management estimates and judgments such
          as future prices of crude oil, refined products and chemical products
          and production profile. However, the impairment reviews and
          calculations are based on assumptions that are consistent with the
          Group's business plan. These assumptions also include those relative
          to the pricing regulations by the regulatory agencies in China that
          the policies will not restrict the profit margins of refined products
          to levels that will be insufficient to recover the carrying cost of
          the related production assets. Favourable changes to some assumptions
          might have avoided the need to impair any assets in these periods,
          whereas unfavourable changes might have caused an additional unknown
          number of other assets to become impaired.

     (c)  Estimation of asset retirement obligations

          Provisions are recognised for the future decommissioning and
          restoration of oil and gas properties. The amounts of the provisions
          recognised are the present values of the estimated future
          expenditures. The estimation of the future expenditures is based on
          current local conditions and requirements, including legal
          requirements, technology, price level, etc.. In addition to these
          factors, the present values of these estimated future expenditures are
          also impacted by the estimation of the economic life of oil and gas
          properties. Changes in any of these estimates will impact the net
          income and the financial position of the Group over the remaining
          economic life of oil and gas properties.

3.   TURNOVER

     Turnover represents revenues from the sale of crude oil, natural gas,
     refined products and petrochemical products and from the transportation of
     crude oil and natural gas. Analysis of turnover by segment is shown in Note
     11.

12.  SIGNIFICANT DIFFERENCES BETWEEN IFRS AND US GAAP

     The consolidated interim condensed financial statements have been prepared
     in accordance with IFRS, which differ in certain material respects from the
     accounting principles generally accepted in the United States of America (
     'US GAAP"). Such differences involve methods for measuring the amounts
     shown in the financial statements, as well as additional disclosures
     required by US GAAP.

     Effect on income of significant differences between IFRS and US GAAP is as
     follows:

In preparing the summary of differences between IFRS and US GAAP, management is
required to make estimates and assumptions that affect the reported amounts of
assets and liabilities, the disclosure of contingent assets and liabilities, and
the estimates of revenues and expenses. Accounting


                                       14




estimates have been employed in these financial statements to determine reported
amounts, including realisability, useful lives of tangible and intangible
assets, income taxes and other factors. Actual results may differ from those
estimates.

A summary of the principal differences and additional disclosures applicable to
the Group is set out below:

(a)  Revaluation of property, plant and equipment

     The property, plant and equipment, excluding oil and gas reserves,
     transferred to the Company by CNPC were appraised as of June 30, 1999, as
     required by the relevant PRC regulations, by a firm of independent valuers
     registered in the PRC, China Enterprise Appraisal. As at September 30,
     2003, a revaluation of the Group's refining and chemical production
     equipment was undertaken by a firm of independent valuers registered in the
     PRC, China United Assets Appraiser Co., Ltd, on a depreciated replacement
     cost basis.

     The June 1999 revaluation resulted in RMB80,549 million in excess of the
     prior carrying value and a revaluation loss of RMB1,122 million on certain
     property, plant and equipment.

     The September 2003 revaluation resulted in a RMB872 million in excess of
     the carrying value of certain property, plant and equipment immediately
     prior to the revaluation and a revaluation loss of RMB1,257 million.

     The depreciation charge, which includes impairment charge, on the
     revaluation surplus from January 1, 2006 to June 30, 2006 was RMB2,340
     million, and from January 1, 2005 to June 30, 2005 was RMB3,436 million.

     The depreciation charge, which includes impairment charge, on the
     revaluation loss from January 1, 2006 to June 30, 2006 was RMBNil, and from
     January 1, 2005 to June 30, 2005 was RMB127 million.

     The loss on disposal of revalued property, plant and equipment from January
     1, 2006 to June 30, 2006 was RMB21 million, and from January 1, 2005 to
     June 30, 2005 was RMB2 million.

     For purposes of reconciling to the US GAAP financial data, the effect of
     the revaluation, the related depreciation charges and loss on disposal is
     reversed. A deferred tax asset relating to the reversal of the effect of
     revaluation in 1999 is established, together with a corresponding increase
     in the shareholders' equity. Under a special approval granted by the
     Ministry of Finance, the effect of the revaluation in 1999 is available as
     additional depreciation base for purposes of determining taxable income.

(b)  One-time remedial payments for staff housing

     The Ministry of Finance of the PRC issued several public notices and
     regulations during the years ended December 31, 2000 and 2001 with respect
     to the one-time remedial payments for staff housing payable to certain
     employees who joined the workforce prior to December 31, 1998 and have
     housing conditions below local standards as determined in accordance with
     government regulations and guidelines. These Ministry of Finance notices
     and regulations also provided that the portion of remedial payments
     attributable to the periods prior to a restructuring of the employer
     enterprise from a wholly state-owned status to a less than wholly
     state-owned status is to be borne by the state shareholder of the
     enterprise.

     The restructuring that resulted in the formation of the Group took place in
     November 1999. As such, the one-time remedial housing payments payable to
     the eligible employees of the Group are to be borne by the state
     shareholder of the Group.


                                       15



     Under IFRS, such direct payments to employees or reimbursements will not be
     recorded through the consolidated profit and loss account of the Group. US
     GAAP contains no such exemption but requires this principal shareholder's
     action on behalf of the Company to be recorded in the consolidated profit
     and loss account. In the last quarter of year 2002, the Group and CNPC
     completed the process of estimating the amount payable to qualified
     employees of the Group. This amount, RMB2,553 million, was reflected in
     determining net income of the Group for the year ended December 31, 2002,
     under US GAAP. Since this amount is borne by CNPC, a corresponding amount
     has been included as an addition to the other reserves in the shareholders'
     equity of the Group. There were no significant changes in this estimate
     during 2005 and the first half of 2006.

(c)  Minority interest

     In accordance with the revised International Accounting Standard 1
     "Presentation of Financial Statements" and International Accounting
     Standard 27 'Consolidated and Separate Financial Statements", minority
     interest becomes part of the profit for the period and total equity of the
     Group, whereas under US GAAP, it is respectively excluded from the net
     income and shareholder's equity of the Group. In addition, the reconciling
     item also includes the impact of minority interest's share of the
     revaluation gain and loss, on the property, plant and equipment of
     non-wholly owned subsidiaries, to net income and shareholders' equity under
     US GAAP.

(d)  Purchase from minority interest of listed subsidiaries

     The Company acquired certain outstanding A shares from the minority
     interest of Jinzhou Petrochemical Company Limited ('JPCL') and Liaohe Jinma
     Oilfield Company Limited ("LJOCL'), A Shares and H Shares (including ADS)
     from minority interest of Jilin Chemical Industrial Company Limited
     ('JCIC'). Under IFRS, the Company applies a policy of treating transactions
     with minority interest as transactions with equity participants of the
     Group. Therefore, the assets and liabilities of JPCL, LJOCL and JCIC
     additionally acquired by the Company from minority interest were recorded
     by the Company at cost. The difference between the Company's purchase cost
     and the book value of the interests in JPCL, LJOCL and JCIC acquired by the
     Company from minority interest was recorded in equity. Under US GAAP, the
     acquisition of additional minority interest is accounted for under purchase
     method. Assets and liabilities additionally acquired were restated to fair
     value and the excess of purchase cost over fair value of the minority
     interest acquired and identified intangible assets was recorded as
     goodwill. Additional depreciation charges were provided for the assets
     which were restated to fair value.

(e)  Recent US accounting pronouncements

     In February 2006, the Financial Accounting Standards Board ("FASB') issued
     Statement No. 155, 'Accounting for Certain Hybrid Financial Instruments"
     ("FAS 155'), which improves financial reporting by eliminating the
     exemption from applying FAS 133 to interests in securitised financial
     assets so that similar instruments are accounted for similarly regardless
     of the form of the instruments and allows a preparer to elect fair value
     measurement at acquisition, at issuance, or when a previously recognised
     financial instrument is subject to a remeasurement (new basis) event, on an
     instrument-by-instrument basis, in cases in which a derivative would
     otherwise have to be bifurcated. Providing a fair value measurement
     election also results in more financial instruments being measured at what
     the FASB regards as the most relevant attribute for financial instruments,
     fair value. FAS 155 is effective for all financial instruments acquired or
     issued after the beginning of an entity's first fiscal year that begins
     after September 15, 2006. The Group is currently evaluating the impact of
     this standard on its financial position and results of operations.


                                       16


     In March 2006, the FASB issued Statement No. 156, 'Accounting for Servicing
     of Financial Assets" ("FAS 156'), which requires all separately recognised
     servicing assets and servicing liabilities be initially measured at fair
     value. FAS 156 permits, but does not require, the subsequent measurement of
     servicing assets and servicing liabilities at fair value. Adoption is
     required as of the beginning of the first fiscal year that begins after
     September 15, 2006. Early adoption is permitted. The adoption of FAS 156 is
     not expected to have a material effect on the Group's financial position or
     results of operations.

     In July 2006, the FASB issued Interpretation No. 48. "Accounting for
     Uncertainty in Income Taxes--an Interpretation of FASB Statement No. 109"
     ('FIN 48'). FIN 48 prescribes a comprehensive model for recognising,
     measuring, presenting and disclosing in the financial statements uncertain
     tax positions that the Group has taken or expects to take in its tax
     returns. The provisions of FIN 48 are effective for the Group on January 1,
     2007, with the cumulative effect of the change in accounting principle, if
     any, recorded as an adjustment to opening retained earnings. The Group does
     not expect the adoption of FIN 48 to have a material impact on the Group's
     financial position or results of operations.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

The following discussion should be read in conjunction with the consolidated
interim condensed financial statements for the Group and the notes thereto to be
submitted to The Stock Exchange of Hong Kong Limited ('HKSE') for publication
on the website of the HKSE, which contains information required under paragraphs
46(1) to 46(9) of Appendix 16 to the Rules Governing the Listing of Securities
on The Stock Exchange of Hong Kong Limited (the 'Listing Rules").

Overview

For the six months ended June 30, 2006, profit before taxation of the Group was
RMB115,918 million, representing an increase of 28.6% compared with the
corresponding period of last year. Net profit was RMB80,681 million,
representing an increase of 29.4% from the corresponding period in last year.
The continued improvement of the Group's operating results was primarily due to
the Group's ability to take full advantage of the opportunities presented by
persistently high oil prices and strong market demand by strengthening its
efforts in exploration and development, the optimal use of its competitive edge
in upstream activities, streamlining of its downstream product mix, unifying
resources allocation, accelerating the construction and interconnection of major
pipelines, the steady promotion of international operations, enhancement of
operational management and the continuous efforts in technological and
managerial innovations.

For the six months ended June 30, 2006, the Group's basic and diluted earnings
per share was RMB0.45 (for the six months ended June 30, 2005: RMB0.35).

Comparison between the six-month period ended June 30, 2006 and the six-month
period ended June 30, 2005

Consolidated Operating Results

Turnover Turnover increased 25.3% from RMB260,618 million for the six months
ended June 30, 2005 to RMB326,545 million for the six months ended June 30,
2006. This was primarily due to the increases in prices and sales volumes of
certain main products, namely crude oil, natural gas and certain refined
products.


                                       17



Operating Expenses Operating expenses increased 23.8% from RMB170,651 million
for the six months ended June 30, 2005 to RMB211,252 million for the six months
ended June 30, 2006. This was primarily due to an increase in the purchase costs
of crude oil, feedstock oil and refined products from external suppliers and an
increase in taxes other than income tax.

Purchases, Services and Other Expenses Purchases, services and other expenses
increased 16.3% from RMB96,956 million for the six months ended June 30, 2005 to
RMB112,758 million for the six months ended June 30, 2006. This was primarily
due to (1) an increase in prices of crude oil and feedstock oil from external
suppliers and an increase in the volume purchased from external suppliers in the
reporting period, which resulted in an increase in the purchase costs of crude
oil and feedstock oil; and (2) an increase in the prices of refined products and
an increase in the volume purchased from external suppliers in the reporting
period, which resulted in an increase in the purchase costs of refined products.
In addition, the increase in the refined product supply operation during the
reporting period also resulted in a corresponding increase in purchase expenses.

Employee Compensation Costs Employee compensation costs increased 30.2% from
RMB13,052 million for the six months ended June 30, 2005 to RMB16,993 million
for the six months ended June 30, 2006. This was primarily due to (1) the
improvement in the Company's operating results which led to an increase in the
wages and welfare expenses of staff and workers; and (2) the increase in salary
surcharge as a result of an increase in the base and percentage for calculating
the salary surcharge since the second half of 2005 by the PRC Government. In
addition, the increase of employee compensation costs in the reporting period as
compared to the first half of 2005 was also due to an increase in the number of
employees resulting from an expansion in production capacity.

Exploration Expenses Exploration expenses were RMB8,750 million, essentially at
the same level as RMB8,729 million for the six months ended June 30, 2005.

Depreciation, Depletion and Amortisation Depreciation, depletion and
amortisation increased 12.1% from RMB26,678 million for the six months ended
June 30, 2005 to RMB29,910 million for the six months ended June 30, 2006. This
was primarily due to an increase in the gross carrying amount of property, plant
and equipment and the average net value of oil and gas assets which led to a
corresponding increase in depreciation and depletion during the reporting
period.

Selling, General and Administrative Expenses Selling, general and administrative
expenses increased 28.2% from RMB14,902 million for the six months ended June
30, 2005 to RMB19,104 million for the six months ended June 30, 2006. This was
primarily due to (1) an increase in the transportation volume which led to an
increase of freight expenses; and (2) an increase in the technological
development expenses resulting from intensified technological development
efforts.

Taxes other than Income Tax Taxes other than income tax increased 115.6% from
RMB11,253 million for the six months ended June 30, 2005 to RMB24,259 million
for the six months ended June 30, 2006. This was primarily due to (1) the
imposition by the PRC government of a special levy on the petroleum exploration
enterprises from March 2006 which is payable by them on the portion of income
realised from the domestic sales of crude oil at prices higher than a specific
level, leading to a substantial increase in the amount of taxes payable by the
Company compared with the first half of 2005; (2) an increase in consumption tax
and surcharges as a result of an increase in the output volume of gasoline and
diesel oil; and (3) an increase in compensation fees for mineral resources due
to an increase in crude oil and natural gas revenue. In addition, an increase of
the natural resource tax rates by the PRC government since the second half of
2005 and the increased oil and gas output in the reporting period also
contributed to the increase of natural resources tax.

Profit from Operations As a result of the factors discussed above, profit from
operations increased 28.2% from RMB89,967 million for the six months ended June
30, 2005 to RMB115,293 million for the six months ended June 30, 2006.


                                       18



Net Exchange Gain Net exchange gain increased from RMB18 million for the six
months ended June 30, 2005 to RMB32 million for the six months ended June 30,
2006. This was primarily due to an appreciation of Renminbi against the US
Dollar during the first half of this year.

Net Interest Expenses Net interest expenses increased 8.8% from RMB817 million
for the six months ended June 30, 2005 to RMB889 million for the six months
ended June 30, 2006. This increase reflects an increase in the carrying amount
of the asset retirement obligations that incurs with the passage of time, which
led to a corresponding increase in the interest expense.

Profit Before Taxation Profit before taxation increased 28.6% from RMB90,169
million for the six months ended June 30, 2005 to RMB115,918 million for the six
months ended June 30, 2006.

Taxation Taxation increased 21.6% from RMB25,229 million for the six months
ended June 30, 2005 to RMB30,675 million for the six months ended June 30, 2006.
This was primarily due to an increase in taxable profits.

Net Profit As a result of the factors discussed above, net profit increased
29.4% from RMB62,363 million for the six months ended June 30, 2005 to RMB80,681
million for the six months ended June 30, 2006.

Segment Information

Exploration and Production

Turnover Turnover increased 38.8% from RMB152,024 million for the six months
ended June 30, 2005 to RMB211,012 million for the six months ended June 30,
2006. This was primarily due to an increase in prices and sales volume of crude
oil and natural gas. During the first half of 2006, the Group's average realised
crude oil price was US$58.75 per barrel, representing an increase of 35.6% from
US$43.33 per barrel for the first half of 2005.

Inter-segment sales revenue increased 40.6% from RMB121,484 million for the six
months ended June 30, 2005 to RMB170,761 million for the six months ended June
30, 2006. The increase was mainly due to an increase in prices and sales volume
of crude oil and natural gas.

Operating expenses Operating expenses increased 37.6% from RMB62,901 million for
the six months ended June 30, 2005 to RMB86,560 million for the six months ended
June 30, 2006. This was mainly due to the increase in taxes other than income
tax, purchase expenditure and staff costs.

Profit from Operations As a result of the factors discussed above, profit from
operations increased 39.6% from RMB89,123 million for the six months ended June
30, 2005 to RMB124,452 million for the six months ended June 30, 2006.

Refining and Marketing

Turnover Turnover increased 27.0% from RMB200,883 million for the six months
ended June 30, 2005 to RMB255,106 million for the six months ended June 30,
2006. The increase was primarily due to an increase in prices and changes in
sales volume of key refined products, of which:

Sales revenue from gasoline increased 6.3% from RMB54,570 million for the six
months ended June 30, 2005 to RMB57,985 million for the six months ended June
30, 2006. The increase was mainly due to an increase in prices of gasoline. The
average realised selling price of gasoline increased 21.4% from RMB3,943 per ton
for the six months ended June 30, 2005 to RMB4,785 per ton for the six months
ended June 30, 2006. The sales volume of gasoline dropped 12.4% from 13.84

months ended June 30, 2005 to RMB101,637 million for the six months ended June
30, 2006. The increase was mainly due to an increase in prices and sales volume
of diesel. The average realised selling price of diesel increased 21.0%


                                       19

for the six months ended June 30, 2005 to RMB268,995 million for the six months
ended June 30, 2006. The increase was primarily due to an increase in the
expenditure on the purchase of crude oil, feedstock oil and refined products
from external suppliers, and an increase in selling, general and administrative
expenses. In addition, the increase in the level of supply operations of oil
products during the reporting period led to a corresponding increase in
operating expenses.

RMB13,889 million for this segment and for the six months ended June 30, 2005,
there was a loss of RMB5,949 million. The losses were mainly as a result of the
effect of the macroeconomic control in China of the prices of the refined
products, resulting in the selling prices of the refined products in China not
in line with the selling prices of the refined products in the international
market.

Chemicals and Marketing

Turnover Turnover increased 6.8% from RMB37,035 million for the six months ended
June 30, 2005 to RMB39,565 million for the six months ended June 30, 2006. The

natural gas and an increase in the sales volume and the average price of
pipeline transmission of natural gas.

Operating expenses Operating expenses increased 31.3% from RMB10,396 million for
the six months ended June 30, 2005 to RMB13,646 million for the six months ended

expenses and an increase in depreciation charges.

Profit from Operations As a result of the factors discussed above, profit from
operations increased 210.4% from RMB1,478 million for the six months ended June
30, 2005 to RMB4,587 million for the six months ended June 30, 2006.

Liquidity and Capital Resources

For the six months ended June 30, 2006, the Group's primary sources of funds
were cash generated from operating activities, short-term borrowings and
long-term borrowings. The Group's funds were used for operating activities,
capital expenditures, repaying short-term and long-term borrowings, acquisition
of subsidiaries and distribution of dividends to shareholders of the Company.

As at June 30, 2006, short-term debts represented approximately 5.1% of the
Group's capital employed as compared with approximately 4.7% as at December 31,
2005. Our ability to obtain adequate financing may be affected by our financial
position and operating results and the conditions of the domestic and foreign
capital markets. The Company must seek approvals from the relevant PRC
government authorities before raising funds in the domestic and foreign capital
markets. In general, the Company must obtain PRC government approvals for any
project involving significant capital investments in our Refining and Marketing
segment, Chemicals and Marketing segment and the Natural Gas and Pipeline
segment.

The Group plans to fund its capital and related investments principally from the
cash generated from operating activities and short-term and long-term
borrowings. For the six months ended June 30, 2006, net cash generated from
operating activities was RMB100,825 million. As at June 30, 2006, the Group had
cash and cash equivalents of RMB92,630 million. Cash and cash equivalents were
mainly denominated in Renminbi (Renminbi accounted for approximately 96.8%, US
Dollar accounted for approximately 2.8%, and HK Dollar accounted for 0.4%).

Cash flows from operating activities

In the first half of 2006, the Group's net cash from operating activities
increased 2.7% from RMB98,167 million for the six months ended June 30, 2005 to
RMB100,825 million for the six months ended June 30, 2006. This was mainly due
to an increase in profit which give rise to an increase in cash flows generated
from operating activities. In addition, an increase in inventories partly offset
the cash flows generated from operating activities.

As at June 30, 2006, our working capital was RMB47,930 million. As at December
31, 2005, our working capital was RMB22,057 million. The increase in working
capital was primarily due to an increase in receivables and prepayments,
inventories and cash and cash equivalents.

Cash used for financing activities

The Group's net cash used for financing activities increased 12.9% for the six
months ended June 30, 2006 compared with the amount as at the six months ended
June 30, 2005. This was mainly due to more cash dividends paid in respect of the
ordinary shares for the first half of this year as compared with the
corresponding period of last year.

On August 23, 2006, the Board of Directors of the Company approved the entering
into the acquisition agreement whereby CNPC E&D will acquire a 67% ownership
interest in PetroKazakhstan Inc. ("PKZ") from CNPC International Ltd. ('CNPCI',
a subsidiary of CNODC). Currently, PK is 67% and 33% owned by CNPCI and JSC
National Company Kazmunaigaz ("KMG') respectively. A total cash consideration
for this acquisition is expected to be approximately US$2,735 million. Upon
completion of the acquisition agreement, PK will be accounted for as an
associate of the Company as it is under the joint control by CNPC E&D and KMG.

Foreign Exchange Rate Risk

From July 21, 2005, the PRC government has reformed the Renminbi exchange rate
regime and implemented a regulated floating exchange rate regime based on market
supply and demand with reference to a basket of currencies. However, Renminbi is
still regulated in capital account. The exchange rates of Renminbi are affected
by domestic and international economic developments and political conditions,
and supply and demand for Renminbi. Future exchange rates of Renminbi against
other currencies could vary significantly from the current exchange rates. As
Renminbi is the functional currency of the Company and most of its consolidated
entities, the fluctuation of the exchange rate of Renminbi may have positive or
negative impacts on the operating results of the Group. An appreciation of
Renminbi against US Dollar may decrease the Group's turnover, but the cost for
acquiring imported materials and equipment may also be reduced. A devaluation of
Renminbi against US Dollar may not have a negative impact on the Group's
turnover but may increase the cost for acquiring imported materials and
equipment as well as the debt obligations denominated in foreign currencies of
the Group.

Commodity Price Risk

The Group is engaged in a wide range of petroleum-related activities. The oil
and gas markets are affected by global and regional demands and supplies. Prices
of onshore crude oil are determined with reference to the prices of crude oil on
the international markets. A decline in the prices of crude oil and refined
products could adversely affect the Group's financial position. The Group
historically has not used commodity derivative instruments to hedge against
potential price fluctuations of crude oil and refined products. Therefore, the
Group is exposed to general price fluctuations of oil and gas commodities in
2006 and in future years.


                                       25



Industry Risk

Like other oil and natural gas companies in China, the Group's operating
activities are subject to regulation and control by the PRC government in many
aspects. This regulation and control, such as the granting of exploration and
production licenses, the imposition of industry-specific taxes and levies and
the implementation of environmental and safety standards are expected to have an
impact on the Group's business operations. As a result, the Group may be subject
to fairly significant restrictions when implementing its business strategy,
developing and expanding its business or maximising its profitability. Any
future changes in PRC governmental policies on the oil and natural gas industry
may also affect the Group's business operations.

Employee Compensation

The total employee compensation payable by the Group for the six months ended
June 30, 2006 was RMB11,198 million, being the total salaries of employees
during the reporting period. Compensation of employees is determined according
to industry practice and the actual conditions of the Group, and is based on the
principles of attracting and retaining high-calibre personnel, and motivating
all staff for the realisation of the best results.

The Company's senior management remuneration system links senior management
members' financial interests (including those of executive directors and
supervisors) with the Company's operating results and the market performance of
its shares. All members of the senior management have entered into performance
contracts with the Company. Under this system, the senior management members'
compensation has three components, namely, fixed salaries, performance bonuses
and stock appreciation rights. The variable components account for approximately
70% to 75% of the senior management officers' total potential compensation,
including approximately 0% to 25% forming the performance bonus component and
approximately 50% to 70% forming the stock appreciation rights component.
Variable compensation rewards are linked to the attainment of specific
performance targets, such as net profit, return on capital and cost reduction
targets. The chart below sets forth the components of the total potential
compensation for key officers.

Contingent Liabilities

Information on the Group's contingent liabilities as at June 30, 2006 is as
follows:

Bank and other guarantees

As at June 30, 2006, the Group had contingent liabilities in respect of
guarantees made to CP Finance, a subsidiary of CNPC, and state-controlled bank
from which it is anticipated that no material liabilities will arise.



                                         June 30, 2006   December 31, 2005

                                              ===               ===


Environmental Liabilities

CNPC and the Group have operated in China for many years. China has adopted
extensive environmental laws and regulations that affect the operation of the
oil and gas industry. The outcome of environmental liabilities under proposed or
future environmental legislation cannot reasonably be estimated at present, and
could be material. Under existing legislation, however, management believes that
there are no probable liabilities, except for the amounts which have already
been reflected in the financial statements that will have a material adverse
effect on the financial position of the Group.

Legal contingencies

The Group is the named defendant in certain insignificant lawsuits as well as
the named party in other proceedings arising in the ordinary course of business.
While the outcome of such contingencies, lawsuits or other proceedings cannot be
determined at present, management believes that any resulting liabilities will
not have a material adverse effect on the financial position of the Group.

Leasing of land, roads and buildings

According to the restructuring agreement entered into between the Company and
CNPC in 1999 upon the formation of the Company, CNPC has undertaken to the
Company as follows:

-    CNPC will use its best endeavours to obtain formal land use right
     certificates to replace the entitlement certificates in relation to the
     28,649 parcels of land which were leased or transferred to the Company from
     CNPC, within one year from August, September and October 1999 when the
     relevant entitlement certificates were issued;

-    CNPC will complete, within one year from November 5, 1999, the necessary
     governmental procedures for the requisition of the collectively-owned land
     on which 116 service stations owned by the Company are located; and

-    CNPC will obtain individual building ownership certificates in the name of
     the Company for all of the 57,482 buildings transferred to the Company by
     CNPC, before November 5, 2000.

As at June 30, 2006, CNPC has obtained formal land use right certificates in
relation to 27,400 out of the above-mentioned 28,649 parcels of land and some
building ownership certificates for the above-mentioned buildings, but has
completed none of the necessary governmental procedures for the above-mentioned
service stations located on collectively-owned land. The directors of the
Company confirm that the use of and the conduct of relevant activities at the
above-mentioned parcels of land, service stations and buildings are not affected
by the fact that the relevant land use right certificates or individual building
ownership


                                       28



certificates have not been obtained or the fact that the relevant governmental
procedures have not been completed. In management's opinion, the outcome of the
above events will not have a material adverse effect on the results of
operations or the financial position of the Group.

Group insurance

Except for limited insurance coverage for vehicles and certain assets subject to
significant operating risks, the Group does not carry any other insurance for
property, facilities or equipment with respect to its business operations. In
addition, the Group does not carry any third-party liability insurance against
claims relating to personal injury, property and environmental damages or
business interruption insurance since such insurance coverage is not customary
in China. While the effect of under-insurance on future incidents cannot be
reasonably assessed at present, management believes that it may have a material
impact on the operating results but will not have a material adverse effect on
the financial position of the Group.

Others

On November 13, 2005, explosions occurred at a manufacturing facility of a
branch of the Company located in the Jilin Province. The impact of the accident
is undergoing government investigation. The Company is presumed to bear related
liability according to the investigation results.

Market Review

Crude Oil Market Review

During the first half of 2006, international crude oil prices remained at high
levels due to rapidly expanding demand, insufficient residual supply of crude
oil, intensified geo-political risk, speculation and other factors. The average
prices for WTI, Brent and Minas crude oil in the first half of the year were
US$66.80, US$65.65 and US$65.81 per barrel respectively, representing an
increase of US$15.31, US$16.00 and US$14.94 per barrel or 29.7%, 32.2% and 29.4%
respectively from the corresponding period in last year. Corresponding to the
rise in international oil prices, domestic crude oil prices also increased. The
average realised price was higher than that of the first half of 2005.

Domestic crude oil imports continued to increase during the first half of 2006
with net import volume of 70.33 million tons, representing an increase of 17.6%
from the corresponding period in last year. Domestic crude oil output and the
amount of crude oil processed reached 92.10 million tons and 142 million tons
respectively.

Refined Products Market Review

During the first half of 2006, although the PRC government strengthened its
control on the domestic macroeconomy, demand for refined products still remained
relatively high. In general, resources were tight and market prices continued to
rise and hit new historical highs repeatedly. In the first half of the year,
nominal consumption of refined products increased 7.1% to 85.73 million tons
compared with the corresponding period in last year. By the end of June 2006,
the refined products inventory held by the Company and Sinopec reached 7.88
million tons, representing an increase of 0.54 million tons from the
corresponding period in last year.

The PRC government has made certain adjustments to the prices of domestic
refined products during the first half of 2006. However, under the impact of
international oil prices, the average benchmark prices of gasoline and diesel
were still higher than their levels during the corresponding period of last
year.

Chemical Products Market Review

In the first half of 2006, the sustained rapid economic development in China
resulted in strong demand of chemical products. Market supply of crude oil was
unable to satisfy the increase in demand due to strong demand, limited increase
in supply and the overhaul of facilities. In a climate of persistently high
crude oil prices, chemical products market tended to favour the sellers and the
prices of most chemical products achieved a 10-year record high.


                                       29



Natural Gas Market Review

In the first half of 2006, China's natural gas market has continued to show a
trend of rapid growth. Despite the adoption by the PRC government of a new
pricing regulation for natural gas in December 2005 and further raising the
ex-factory price of natural gas in China, the demand for natural gas has been
growing at an excessive rate and the discrepancy between its supply and demand
remained prominent.

Business Review

For the six months ended June 30, 2006, total oil and gas output of the Company
was 533.2 million barrels of oil equivalent, including 419.1 million barrels of
crude oil and 684.7 billion cubic feet of marketable natural gas, representing
an average daily crude oil output of 2.32 million barrels and an average daily
marketable natural gas output of 3,783 million cubic feet. A total of 417
million barrels of crude oil and 653.5 billion cubic feet of natural gas were
sold during the six months ended June 30, 2006. The Company sold approximately
84.8% of its crude oil to its refineries. During the first half of 2006, lifting
cost of the Company was US$5.91 per barrel, compared with the lifting cost of
US$5.10 per barrel in the first half of 2005.

For the six months ended June 30, 2006, the Company's refineries processed 393
million barrels of crude oil, representing an average daily processed output of
2.17 million barrels. The Exploration and Production segment provided
approximately 83.0% of the crude oil processed by the Company's refineries. The
Company produced approximately 34.30 million tons of gasoline, diesel and
kerosene and sold approximately 37.35 million tons of these products. The
Company is actively expanding its sales network, and its retail network in
particular, by taking advantage of the complementary value-added effect of the
integration of Refining and Marketing segment. As at June 30, 2006, there were
17,952 service stations either owned, controlled or franchised by the Company or
owned by CNPC but to which the Company provided supervisory support. The cash
processing cost of the Company's refineries has arisen from RMB126 per ton
during the first half of 2005 to RMB151 per ton for the same period of 2006.

For the six months ended June 30, 2006, the Company produced 1.003 million tons
of ethylene, 1.525 million tons of synthetic resin, 0.628 million tons of
synthetic fibre raw materials and polymers, 0.155 million tons of synthetic
rubber, and 1.737 million tons of urea.

The Natural Gas and Pipeline segment is the Company's core business segment for
development. For the six months ended June 30, 2006, the Company sold 566.8
billion cubic feet of marketable natural gas through its Natural Gas and
Pipeline segment. As at June 30, 2006, the Company owned and operated 20,340
kilometers of regional natural gas pipeline network, of which 19,212 kilometers
of the pipeline network were operated by the Natural Gas and Pipeline segment.
The Company owned and operated 9,391 kilometers of crude oil pipeline and owned
2,460 kilometers of refined products pipeline.

The Second Half of 2006 and Beyond

In the first half of 2006, in an environment characterised by strong domestic
demand for oil and gas, the Company advanced its main operations in an active
and orderly manner and improved the micro- management of its production. As a
result, the principal production and operation targets were achieved and new
breakthroughs occurred in various aspects of operations. Various significant
achievements were made in the efforts of oil and gas exploration, leading to a
sustainable increase in oil and gas reserves of the Company. Crude oil
processing volume has achieved steady growth which further improved the major
techno-economical indices. The Company strived to produce more value added
products in its chemical production, leading to an effective increase in the
competitiveness of its major products. The construction of major oil and gas
pipelines was progressing smoothly and certain key projects have been completed
and have commenced operations.


                                       30



In the second half of 2006, the Company anticipates that it will continue to
enjoy a generally favorable macroeconomic environment. The Company plans to
steadily coordinate its production and business operations according to the work
plans formulated at the beginning of the year. The Company plans to continue
'prioritising safety and environment and people orientation", further strengthen
safety and environmental protection, emphasise the creation of corporate harmony
and actively fulfill its social duties. The Company aims to fully achieve the

comprehensive management of mature oilfields, enlarge production capacity in new
regions and carefully coordinate production and operations as well as the
linkage and management of different stages of operations; ensure that the annual
targets of oil and gas reserves volume and production plans will be achieved.

In the Refining and Marketing area, the Company plans to steadily coordinate
refining and production, and consistently improve marketing quality and returns;
further optimise the overall refining layout to ensure that key refining
construction projects are implemented as scheduled; strengthen the management of
the overall control of the production process, improve the stability rate and
effective rate of the operation of facilities to ensure safe and reliable
production; improve the linkage of production, transportation and marketing,
enlarge end-user sales volume and improve sales quality and operation returns;
leverage on the strength of integrated refining, continue to improve the
chemical product mix and increase the proportion of high quality and high value
added products, aiming to maximise the overall returns.

In the Natural Gas and Pipeline area, the Company plans to organise natural gas
production and marketing in a systematic manner, steadily and gradually increase
the construction of major pipelines. The Company plans to proactively grasp the
changes in the use of gas in downstream industries, further strengthen the
balance among production, transmission and sales of natural gas and enhance safe
operation of pipelines.

In its international operations, the Company plans to steadily promote
international business and expand international cooperation, continue to
increase exploration in key regions and actively promote risk explorations;
further develop overseas business, coordinate production in existing regions in
full gear to ensure that the annual targets of oil and gas operational output
and share oil output will be achieved. The Company plans to promote
international trade by actively diversifying imports of resources, consistently
improving trading methods and trading system to enhance the total trade volume
and improve profitability.

In the future, the Company intends to continue seeking to maximise its returns
and value for its shareholders, emphasise main businesses, and continue
developing international businesses and promoting rapid growth in international
operations while intensifying domestic oil and gas exploration and development
