China will raise the retail prices of gasoline by 550 yuan ($85.75) per tonne and diesel by 540 yuan per tonne starting Tuesday, the country's top economic planner announced on Monday.

The benchmark retail price of gasoline will be lifted by 0.41 yuan per liter and diesel by 0.46 yuan per liter, according to a statement posted on the website of the the National Development and Reform Commission.

The price hike, which marks the second such increase in a month and the fourth this year, comes amid rising pressures for the country's refineries as increasing global crude prices keep driving up their operation costs.

Under China's oil product pricing system introduced in 2009, domestic fuel prices may be adjusted when average prices of Brent, Cinta, and Dubai change by more than 4 percent over 22 working days.

China last raised fuel prices on August 10, following three consecutive cuts between May and July.
