rapid growth momentum and domestic demand for refined oil and petrochemical
products remained strong. Influenced by international market, the prices of
crude oil and refined oil products had fluctuated at a fairly high level, and
as the chemical business was going up the cycle, the prices of chemical
products had increased to a certain extent over the same period last year. By
seizing the market opportunities, devoting to increase production volume and
optimizing production operation, the Company has obtained fairly good results
in oil and gas production, the processing volume of crude oil, the sales of
refined oil products and ethylene production etc.





Exploration and Production Segment: In the first quarter of this year, the
Company has achieved good results in terms of exploration, development and oil
and gas production. In respect of exploration, the Company has made
significant achievements in the exploration of concealed oil and gas reserves
in the mature oil fields in eastern China. The exploration in Tahe oilfield
and the surrounding areas in western China has shown good discoveries. In
respect of production, the Company seized the valuable opportunities of higher
crude oil price, adhered to the four unity of "balanced reserves, production,
investment and efficiency", and improved the recovery rate. Oil and gas
production has increased over the same period last year in a stable manner.

Refining Segment: In the first quarter of 2004, the demand for domestic
refined oil products was strong. The Company seized the market opportunities,
optimized resources allocation, adjusted product mix, devoted to increase the
processing volume of crude oil, made full use of the price difference between
sour and sweet crude oil, increased the processing volume of sour crude oil,
and kept the refining facilities in stable operation with high utilization
rate. Meanwhile, the Company was flexible to adapt to market changes and
devoted to expand the sales of oil products other than refined oil products.

Marketing and Distribution Segment: In the first quarter of 2004, the Company
seized the market opportunities of a sustained brisk demand for refined oil
products, coordinated production and sales closely, and arranged resources
production and domestic marketing volume in a reasonable manner. This resulted
in a substantial increase in the sales volume of domestic refined oil
products. At the same time, the Company took measures to raise its retail and
direct distribution volume, which further optimized its sales portfolio.

Chemicals Segment: In the first quarter of 2004, influenced by international
market, the price of both major chemical products and gross margin had
increased to a fairly significant extent. The Company adhered to the marketing
strategy of "focusing on the market, full-load production and low
inventories", adjusted product mix and optimized marketing structure, and kept
major chemical plants in full-load production. The production volume of major
chemical products such as synthetic resin, synthetic rubber, monomer and
polymers for synthetic fibers has increased significantly. The production
volume of high added value products like performance compound resins and
differential fibers has further increased.

Significant changes and explanations:

o     Profit from principal operations

      The percentage of profit from principal operations to the profit before
      taxation was 209.63%, representing a decrease of 59.29 percentage points
      over 268.92% of the previous year. This was largely due to the fact that
      although profit from principal operations has increased by 24.25% over
      the quarterly average value of RMB 20.179 billion of the previous year;
      expenses in the reporting period had a slight increase of 3.20% over the
      quarterly average value of the previous year; profit before taxation had
      an increase of 59.39% over the quarterly average of the previous year;
      and profit before taxation attained a higher growth than profit from
      principal operations.

      The major reason for the increase in profit from principal operations
      and profit before taxation is that prices for crude oil, refined oil
      products and chemical products were still on a high level in the first
      quarter of 2004. The Company seized opportunities of the high demand for
      refined oil and chemical products, devoted to develop the market, and
      raised its sales volume. At the same time, profit from principal
      operations increased substantially, and the total margin ratio increased
      from 19.47% in the first quarter of 2003 to 20.30% in the first quarter
      of 2004, especially the chemicals margin ratio which rapidly increased
      from 10.46% in the first quarter of 2003 to 20.88% in the first quarter
      of 2004.

o     Expenses in the reporting period

      Expenses in the reporting period amounted to RMB 11.884 billion,
      accounting for 99.36% of the profit before taxation, and representing a
      decrease of 54.11 percentage points over 153.47% of the previous year.
      This is mainly due to the fact that expenses in the reporting period
      rose slightly by 3.2% as compared with the quarterly average value of
      the previous year. Affected by the higher refining and chemicals gross
      margin ratio, profit before taxation has increased by 59.39% as compared
      with the quarterly average value of the previous year.
