International crude oil prices maintained at a high level and continuously reached unprecedented record level and prices of chemical products continue to soar. Faced with the changes in the operating environment, the Company planned in a scientific manner and responded actively, and realised a continuous development in the principal operations of the Group, stable production and operation, steady increase in the output of major products and further enhancement of the sustainability of the Group. Excluding the impacts resulted from policy factors such as the special levy on domestic crude oil sales and the macro economic controls on the prices of refined products, the efficacy of the Company's operation continues to maintain at a higher level. In respect of exploration and production, the Group carried out exploration at the key basins and focused on key exploration projects, enhanced the exploration of mature oilfields and ventured into the exploration of new oilfields actively. The Group realised overall discovery and development of new oilfields, fully activated secondary recovery of mature oilfields, and conducted production in the oilfields in a safe, steady and orderly manner. During the first quarter of 2008, the crude oil output of the Group was 216 million barrels and the marketable natural gas output was 484.7 billion cubic feet, representing an increase of 3.3% and 18.0% from the same period in 2007, respectively. Faced with growing demand in the market, the Group organised refining process meticulously, scientifically modified refining arrangements, and optimised allocation of resources and product mix actively, and thereby realised safe, stable, long-term, full-load and optimised production. Crude oil processing and production of key refined products reached a historically high level. During the first quarter of 2008, the Group's refineries processed 217 million barrels of crude oil, representing an increase of 7.4% from the same period in 2007, produced 18.924 million tonnes of gasoline, diesel and kerosene, representing an increase of 8.8% from the same period in 2007, and produced 709,000 tonnes of ethylene, representing an increase of 9.2% from the same period in 2007. In respect of sales of the refined products, the Group thrived to overcome the adverse impacts resulted from domestic refined product prices being lower than that in the international market and natural disasters including cold weather, rain and snow storms, frost and etc., performed our social responsibilities conscientiously, modified our sales structure and strengthened our operation and management. During the first quarter of 2008, the Group sold 21.865 million tonnes of gasoline, diesel and kerosene, representing an increase of 18.5% from the same period of in 2007. A number of key pipeline constructions developed in an orderly manner, and the Second West-East Pipeline project commenced construction.

---------------------------------------------------------------------------------------------- Net cash flows from financing activities 15,633 293 5,235.5 ---------------------------------------------------------------------------------------------- 7 Explanation of significant changes: The increase in cash at bank and on hand was mainly due to increases in sales income of the Group and the increase in short-term borrowings undertaken for the Group's operations. The increase in notes receivable was mainly due to an increase in sales income. The increase in accounts receivable was mainly due to the expansion of the scale of Group's operations and the increase in sales income. The increase in advances to suppliers was mainly due to increased capital expenditure and also reflects increases in the prices of raw materials and supplies. The increase in short-term borrowings was mainly due to the additional loans undertaken for the Group's operations. The increase in dividends payable was mainly due to dividends that have been declared in the first quarter of 2008 but have not been distributed by the subsidiaries of the Group to the minority interest. The increase in other payables was mainly due to increase in liabilities incurred during the period and increases in safety fund accrual. The increase in the current portion of non-current liabilities was mainly due to an increase in long-term borrowings becoming due within a year partially offset by repayment of the current portion of non-current liabilities in the three months ended March 31, 2008. The increase in operating income was mainly due to increases in selling prices and increases of sales volume of major products of the Group. The increase in cost of sales was mainly due to an increase in the purchase prices of crude oil, feedstock oil and other raw materials from external suppliers as well as an expansion in the production scale of the Group. The increase in tax and levies on operations was mainly due to increases in the payment of the special levy on the sale of domestic crude oil by the Group. The decrease in taxation was mainly due to both a lower level of profit in the three months ended March 31, 2008 compared with the same period in 2007 as well as a reduced corporate income tax rate. The decrease in the net profit attributable to equity holders of the Company reflects the effect of the factors discussed above in relation to the income statement items. The increase in the net profit attributable to minority interest was mainly due to the expansion and the increase in profit of the subsidiaries of the Group. The decrease in net cash flows from operating activities was mainly due to the increase in cash received from sales of goods and rendering of services being less than that offset by the cash paid for goods and services purchased. The decrease in net cash flows used for investing activities was mainly due to a reduction in capital expenditures paid in cash. 8 The increase in net cash flows from financing activities was mainly due to increases in capital contributions to subsidiaries from minority interest as well as a net increase in short-term borrowings undertaken by the Group for the Group's operations. 3.2 Significant events and their impacts as well as the analysis and explanation for the solutions [x] Applicable [ ] Inapplicable -------------------------------------------------------------------------------- 1.

Significant differences between CAS and IFRS The financial statements of the Group prepared in accordance with CAS differ in certain material aspects from those in accordance with IFRS. A statement of reconciliation of such differences is set out below: ----------------------------------------------------------------------------------------------------------- For three months ended March 31, 2008 2007 ----------- ----------- Notes RMB million RMB million ----------------------------------------------------------------------------------------------------------- Consolidated profit for the period under IFRS 33,585 44,422 Adjustments: Depletion of oil and gas properties (1) (1,597) (2,477) Amortisation of revaluation for assets other than fixed assets and oil and gas properties in 1999 (2) (37) (19) Depreciation and depletion of revaluation for fixed assets and oil and gas properties in 2003 (3) (59) (29) Difference on disposal of non-current assets related to the reversal of reversed impairment for non-current assets (4) 5 -- Reversal of safety fund accrued under CAS which does not meet the definition of a liability under IFRS (5) (1,596) -- Other 6 (93) Deferred taxation (6) 752 (2,715) ----------- ----------- Consolidated profit for the period under CAS 31,059 39,089 =========== =========== ----------------------------------------------------------------------------------------------------------- 28 -------------------------------------------------------------------------------------------------------- March 31, December 31, 2008 2007 ----------- ------------ Notes RMB million RMB million -------------------------------------------------------------------------------------------------------- Consolidated shareholders' equity under IFRS 813,194 776,347 Adjustments: Depletion of oil and gas properties (1) (81,259) (79,662) Revaluation, amortisation of and disposal of assets other than fixed assets and oil and gas properties revalued in 1999 (2) 372 409 Revaluation, and depreciation and depletion of fixed assets and oil and gas properties revalued in 2003 (3) 278 337 Reversal of reversed impairment for non-current assets and related difference on disposal of such non-current assets (4) (87) (92) Reversal of safety fund accrued under CAS which does not meet the definition of a liability under IFRS (5) (5,155) (3,559) Currency translation differences (38) (390) Other 531 525 Deferred taxation (6) 21,908 21,156 ------------ ------------- Consolidated shareholder's equity under CAS 749,744 715,071 ============ ============= -------------------------------------------------------------------------------------------------------- (1) Depletion of oil and gas properties is provided using the unit of production method under IFRS, while the straight-line method is used under CAS. (2) During the restructuring of CNPC and establishment of the Company in 1999, a valuation was carried out on June 30, 1999 for the assets and liabilities CNPC invested in the Company. The valuation results from China Enterprise Appraisals are all recognised in the financial statements under CAS. However, in the financial statements under IFRS, revaluation model is used in subsequent measurement by the Group only for fixed assets and oil and gas properties. Consequently, valuation results other than for fixed assets and oil and gas properties are not recognised in the financial statements under IFRS. (3) As the revaluation model is used in subsequent measurement for fixed assets and oil and gas properties by the Group under IFRS, revaluations were carried out by independent appraisers with sufficient regularity. In order to meet the requirements of IFRS, on September 30, 2003, a revaluation of the Group's refining and chemical production equipment was undertaken by a firm of independent valuers, China United Assets Appraiser Co., Ltd., in the PRC on a depreciated replacement cost basis. The results of the revaluation were recognised in the financial statements under IFRS. However, fixed assets and oil and gas properties are recognised using the historical cost model under CAS. Consequently, these revaluation results were not recognised in the financial statements under CAS. 29 (4) Under CAS, once recognised, any impairment losses for long-term assets, such as fixed assets, oil and gas properties, intangible assets and long-term equity investments, cannot be reversed in subsequent accounting periods. However, under IFRS, if there are changes to the factors which resulted in the original impairment of the long-term asset which result in the recoverable amount being higher than the carrying amount the impairment loss previously recognised shall be reversed. (5) In accordance with the "Temporary regulation for safety expense financial management of high risk industry" issued by the Ministry of Finance and State Administration of Work Safety of PRC, a safety fund has been accrued for the Group's oil and gas exploration, refinery and chemical production activities within the PRC from January 1, 2007. This safety fund has been recognised into the Group's income statement. The accrued safety fund will be used for improving the safety conditions of production. As the Group did not have a specific utilisation plan for this accrued safety fund as at March 31, 2008, it was reversed under IFRS. (6) The consequences of (1)-(5) and other differences between IFRS and CAS on deferred taxation. 30
