BEIJING — China will reduce the retail prices of gasoline and diesel starting on Aug 7, the country's top economic planner said on Aug 6.

Based on recent changes in international oil prices, the retail prices of gasoline and diesel will be reduced by 80 yuan (about $11.37) and 70 yuan per tonne respectively, according to the National Development and Reform Commission (NDRC).

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.

The NDRC also demanded that major oil companies, including China National Petroleum Corporation, China Petrochemical Corporation and China National Offshore Oil Corporation, work to ensure stable supply and implement the national pricing policy.

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