BEIJING — China will lower the retail prices of gasoline and diesel from Oct 22, the country's top economic planner said on Oct 21.

Based on recent changes in international oil prices, the retail prices of gasoline and diesel will be reduced by 150 yuan (about $21.2) and 145 yuan per tonne respectively, according to the National Development and Reform Commission.

Under the current pricing mechanism, if international crude oil prices change by more than 50 yuan per tonne and remain at that level for 10 working days, the prices of refined oil products such as gasoline and diesel in China will be adjusted accordingly.

International crude oil prices slumped during the latest price adjustment period, and might see short-term fluctuations ahead, the commission said.

China's three biggest oil companies, namely China National Petroleum Corporation, China Petrochemical Corporation and China National Offshore Oil Corporation, have been asked to maintain oil production and facilitate transportation to ensure stable supplies.

The economic planner said it would closely monitor the effects of the current pricing mechanism and make improvements in response to global fluctuations.
