      2.4.        Business review

            In the first quarter of 2005, the Chinese economy continued to
            maintain growth and domestic demand for refined oil products and
            petrochemical products remained strong. International prices of
            crude oil had fluctuated at a fairly high level. By adopting
            various measures to increase production volume and optimise
            operations in respond to the changing market, the Company obtained
            reasonably good operating results in various areas, including oil
            and gas production, processing volume of crude oil, sales volume
            of refined oil products and ethylene production.

            Exploration and Production Segment: the Company has made further
            efforts in exploration and development. Significant achievements
            have been made in exploration of concealed oil and gas reserves in
            the mature oil fields in eastern China. The exploration in the
            Tahe oilfield in western China has shown good discoveries. During
            the period, the Company accelerated the pace of construction for
            the increase of production capacity in major areas. Oil production
            was stable and gas production increased over the same period last
            year.

            Refining Segment: under the backdrop of pricing control over oil
            products in domestic market, the Company optimised refining
            process and resources allocation, adjusted product mix and
            increased the production of high value-added products. In
            addition, resources allocation and transportation were optimized
            and the price difference between sour and sweet crude oil was
            taken advantage of, processing volume of sour crude oil was
            increased and stable operation of the refining facilities which
            had been operated at a high utilization rate was maintained.

            Marketing and Distribution Segment: the Company coordinated
            production and sales closely in an effort to meet the strong
            demand for oil products in domestic market, which resulted in a
            increase in its domestic sales volume of refined oil products. At
            the same time, the Company took measures to raise its retail and
            distribution volume, which resulted in the steady increase in the
            proportion of retail and distribution sales as a percentage of
            total domestic sales.

            Chemicals Segment: the Company adhered to the marketing strategy
            of "focusing on market, full-load production and low inventories".
            It also strives to adjust its product mix and optimise its
            marketing structure. During the period, the production of major
            chemical products such as synthetic resin, synthetic rubber,
            monomer and polymers for synthetic fibers has increased
            significantly. The production volume of high value-added products
            such as performance compound resins and differential fibers also
            experienced further increase. In the first quarter of 2005,
            production has been commissioned for the Secco ethylene project.

      Significant changes and explanations:

      o  Profit from principal operations

            The percentage of profit from principal operations to the profit
            before taxation was 189.78%, representing a decrease of 25.45
            percentage points from 215.23% of the same period of the previous
            year. This was mainly due to the fact that the prices of crude
            oil, refined oil products and chemical products were still at high
            level in the first quarter of 2005. The Company also seized the
            market opportunities of strong demand for refined oil products and
            chemical products and was devoted to expand the market and
            increase its sales volume. Despite the significant increase in
            income from principal operations, the percentage increase in
            income from sales of goods was less than the percentage increase
            in the cost of raw materials and, as a result, profit from
            principal operations experienced a slight decrease of 0.56% over
            the quarterly average value of RMB 28.806 billon of the previous
            year; and profit before taxation had an increase of 12.78% over
            the quarterly average of the previous year. Therefore, the profit
            from principal operations accounted for a smaller percentage of
            the total profit before taxation than last year.

      o  Net non-operating income/expenses

            The Company experienced losses on disposal of fixed assets and
            impairment losses on long-lived assets amounted to RMB 8.932
            billion for the year ended 31 December 2004. However, the loss on
            disposal of fixed assets was relatively small in the first quarter
            of 2005.

      outgoing trade amounted to RMB 16.819 billion (including, RMB 16.798
      billion of sales of products and services, RMB 9 million of interest
      earned, RMB 12 million of income from agency fee). During the reporting
      period, the products and services provided by Sinopec Group (purchase,
      storage and transportation, exploration and production services and
      production-related services) to the Company amounted to RMB 14.261
      billion, representing 9.1% of the Company's operating expenses of the
      reporting period; the ancillary and social services provided by Sinopec
      Group to the Company amounted to RMB 433 million, representing 0.3% of
      operating expenses of the reporting period; the product sales from the

3.3.2 Financial statements for the first quarter ended 31 March 2005 prepared

3.3.2.1  Basis of presentation

      Petrochemical"), Zhongyuan Petrochemical Company Limited ("Zhongyuan
      Petrochemical"), Sinopec Group Guangzhou Petrochemical General Plant
      ("Guangzhou Petrochemical") and certain catalyst plants ("Catalyst
      Plants") from Sinopec Group Company (hereinafter referred to as the

      As the Company, Tianjin Petrochemical, Luoyang Petrochemical, Zhongyuan
      Petrochemical, Guangzhou Petrochemical and Catalyst Plants are under the
      common control of Sinopec Group Company, the Acquisition of
      Petrochemical and Catalyst Assets are considered as "combination of

      to a pooling-of-interests ("as-if pooling-of-interests accounting").
      Accordingly, the assets and liabilities acquired from Tianjin
      Petrochemical, Luoyang Petrochemical, Zhongyuan Petrochemical, Guangzhou
      Petrochemical and Catalyst Plants have been accounted for at historical
      cost and the financial statements of the Company for periods prior to
      the combination have been restated to include the results of operations
      of Tianjin Petrochemical, Luoyang Petrochemical, Zhongyuan
      Petrochemical, Guangzhou Petrochemical and Catalyst Plants on a combined
      basis. In connection with these acquisitions, certain assets, primarily
