BEIJING, April 16 (Xinhua) -- China will raise its retail prices of gasoline and diesel from Wednesday, based on recent changes in international oil prices, the country's top economic planner said on Tuesday. Gasoline and diesel prices will increase by 200 yuan (about 28.16 U.S. dollars) and 195 yuan per tonne, respectively, the National Development and Reform Commission announced in a statement. Under China's current pricing mechanism, the 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.
