BEIJING — China will raise the retail prices of gasoline and diesel from May 31, the country's top economic planner said on May 30.

Based on recent changes in international oil prices, the retail prices of gasoline and diesel will rise by 400 yuan (about $59.66) and 390 yuan per metric ton, respectively, according to the National Development and Reform Commission.

The move marks the 10th fuel price increase since the end of last year.

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, gasoline and diesel prices in China will be adjusted accordingly.
