China will reduce the retail prices of gasoline and diesel on Thursday based on recent changes in international oil prices,the country's top economic planner said on Wednesday.

Gasoline prices will be slashed by 135 yuan(about 18.82 U.S.dollars)per tonne and diesel prices by 130 yuan per tonne,according to the National Development and Reform Commission(NDRC).

China's three biggest oil companies--China National Petroleum Corporation,China Petrochemical Corporation and China National Offshore Oil Corporation--as well as other oil refineries,have been directed to effectively organize the production and transportation of refined oil products to ensure stable supplies.

Under the current pricing mechanism,prices of refined oil products are adjusted in accordance with changes in international crude oil prices.

Relevant departments in various regions should intensify market supervision and inspection efforts.Additionally,they should implement strict measures to crack down on activities that violate national price policies to ensure market order,the NDRC said.
