Sinopec Corp. Reports Profit Increase for 1H05

despite Challenging Environment

Beijing, People's Republic of China (PRC) - August 29, 2005 - China Petroleum & Chemical Corporation (“Sinopec Corp" or "the Company") (HKEX: 386; NYSE:SNP; LSE: SNP; CH: 600028) today announced its financial results for the first half of fiscal year 2005.

Under IFRS, the turnover and other operating revenues of the Company totaled RMB 368.45 billion (US$44.50 billion), an increase of 31.85% over the first half of 2004. Profit attributable to equity holders of the parent amounted to RMB 19.65 billion (US$2.37 billion), an increase of 17.36% over the first half of 2004. Earnings per share was RMB 0.227 based on the number of shares outstanding at the end of the reporting period.

Under the PRC Accounting Rules and Regulations, revenues from principal operations totaled RMB 359.24 billion (US$43.39 billion), an increase of 35.20% over the first half of 2004. Net profit totaled RMB 18.04 billion (US$2.18 billion), an increase of 19.98% compared to the first half of 2004. Earnings per share was RMB 0.208 based on the number of shares outstanding at the end of the reporting period.

“During the first half of 2005, international prices of crude oil were very volatile and the price differential between domestic and overseas refined oil products widened further due to the austerity price controls on domestic refined oil products.Such price controls kept domestically refined oil product prices substantially lower than crude oil prices.Despite this challenging environment, the Company successfully managed to deliver fairly strong resultsby optimizing resource allocation, adjusting its corporate structure, strengthening internal management and maximizing the synergies between the energy and petrochemical businesses.” commented Sinopec Corp. Chairman, Chen Tonghai.

The Board of Directors has approved the payment of an interim dividend of RMB 0.04 per share for the first half of 2005. This is equivalent to RMB 4.00 (US$0.48) per American Depositary Share (ADS).

Business Review

Exploration and Production

Crude oil production reached 136.69 million barrels and natural gas production reached 104.8 billion cubic feet, an increase of 0.62% and 4.74% respectively over the same period of 2004.In the first half of 2005, relying on theory and technological innovation, the Company strengthened progressive exploration and focused on pre-exploration in new blocks. Remarkable exploration results were achieved with respect to hidden oil and gas reserves in the mature blocks in Eastern China and important progress was accomplished in exploration in Southwestern China. However, since some exploration wells were not completed by the end of the reporting period, they were not included in the evaluations, resulting in a decline in newly added proved oil and gas reserves evaluated in accordance with SEC rules. At the end of the reporting period, proved oil and gas reserves increased by 0.48% compared to the end of 2004. In the first half of 2005, the average crude price realized by the Company during the first half of 2005 was US$39.40 per barrel, up by 33.0% over the same period last year. The natural gas price realized was US$2.26 per thousand cubic feet, up by 8.70% over the same period last year. The Company increased partial down hole operations in order to stabilize and increase oil and gas production in the older blocks. This, combined with price increases of water and electricity resulted in an increase of 11.15% in lifting cost to US$6.89/barrel compared to the same period last year. The Exploration and Production Segment realized operational returns of RMB 17.80 billion(US$2.15 billion), up by 69.15% over the same period last year.

Total capital expenditure for joint venture projects such as Shanghai Secco amounted to RMB 1.85 billion (US$223million).

Business Prospects

Looking to the second half of 2005, the Company expects that international crude prices will continue to be volatile and the global refining and chemical industry will continue to expand. Domestically, China’s economy should continue to grow rapidly and demand for petroleum and petrochemical products should increase steadily. The adjustment to China’s exchange rate and the minor appreciation of the Renminbi on July 21, 2005 was conducive to lowering crude procurement costs and helped reduce import prices for chemical products. The Company also expects that the Chinese government will continue to tightly control oil product prices.

Confronted with such a complicated market environment, the Company will adopt flexible operating strategiesand minimize operational risks. The Company will particularly focus on the following:

Exploration and Production - the Company intends to implement its resource strategy, accelerate exploration and development, and aim to realize a 100% reserve replacement ratio for the whole year. In addition, the Company will focus on production capacity construction in western Tahe, Shengli shallow sea blocks, etc. Capitalizing on high crude oil prices, the Company will increase the production of high-cost crude oil and proactively develop the natural gas market. In the second half of 2005, the Company plans to produce 140.2 million barrels of crude oil and 109 billion cubic feet of natural gas.

Refining - the Company will closely monitor changes in the international crude oil market, adhere to its strategy of multi-resources of crude, and work to increase the procurement and refining volume of sour and heavy crude to reduce costs. Meanwhile, the Company will make full use of crude oil pipelines and optimize resource flow and allocation to reduce the cost of transportation and storage. Based on market demands, the Company will adjust and optimize its refining plan and product mix to increase the production of high value-added products. Furthermore, the Company plans to reinforce the process technology management of its facilities to ensure safe, stable, and full-load operations. In the second half of 2005, the Company plans to process 72 million tonnes of crude oil.

Marketing and Distribution - the Company will carefully monitor market trends and strive to expand total sales volume of refined products through active sales promotion. In addition, the Company will consolidate the operation management of petrol stations, further increase the throughput per station and increase its share of the end-customer market by improving service quality. The Company will fully utilize its modern logistics system and optimize resource allocation to further reduce transportation costs. Furthermore, the Company will attempt to accelerate the construction of refined oil product pipelines and petrol stations in key areas while adjusting the layout of depots and optimizing its marketing network. The popularization of IC cards will be accelerated to realize the target of “One Card, All Sinopec Stations”. In the second half of 2005, the Company will target its total domestic sales volume of refined oil products at 52 million tonnes, including 30.4 million tonnes of retail volume and 10.6 million tonnes of direct sales volume.

Chemical - the Company will capitalize on the economic expansion cycle, fully exploit its newly built chemical production capacity and ensure full-load operation of its facilities to expand the production of major chemicals. Responding to market trends, the Company will work to increase the production of products that cater to the market and the production of performance compounds and differential fiber. In addition, the Company will concentrate on the newly established chemical sales subsidiary to enhance the overall advantages of chemical production and market competitiveness. In the second half of 2005, the Company plans to produce 2.75 million tonnes of ethylene.

In the second half of 2005, faced with severe challenges despite a favorable market environment, the Company will continue to adhere to the operating strategy of “Reform, Restructuring, Innovation and Development”, taking full advantage of all opportunities to realize the production and operation objectives set for the whole year and deliver sound operation results.
