BEIJING — China will raise the retail prices of gasoline and diesel from March 29, the third increase this year, the country’s top economic planner announced on March 28.

As international oil prices increase, the retail prices of gasoline and diesel will rise by 170 yuan ($27.29) and 165 yuan per ton, 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 ton 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.

Global oil prices rallied this week as traders cheered over a surprise decline in US crude stockpiles.

The benchmark Brent crude broke $70 per barrel for the first time since December 2014.

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

It has asked major Chinese oil companies, including China National Petroleum, China Petrochemical and China National Offshore Oil, to ensure stable supply and pricing.
