BEIJING, Jan. 3 -- China will raise the retail prices of gasoline and diesel from Thursday, based on recent changes in international oil prices, the country's top economic planner said on Wednesday.

Gasoline prices will increase by 200 yuan (about 28.17 U.S. dollars) per tonne, and diesel prices by 190 yuan per tonne, the National Development and Reform Commission said.

Under China's current pricing mechanism, prices of refined oil products are adjusted following changes in international crude oil prices.

China's three biggest oil companies -- the China National Petroleum Corporation, the China Petrochemical Corporation, and the China National Offshore Oil Corporation -- and oil refineries have been directed to maintain oil production and facilitate transportation to ensure stable supplies, the commission said.
