China will raise the gasoline price by 3.8% and raise diesel by 4% beginning Wednesday in the face of rising crude oil prices, despite persistent worries about inflation.

The increase--announced late Tuesday by China's National Development and Reform Commission, the nation's economic planning body--marks the second increase in nearly two months. It also comes after China posted a 5.1% rise in consumer prices in November, the biggest rise since July 2008.

China has taken steps in recent weeks to curb inflation, including price controls, lending limits and increased bank reserve requirements. Officials hope to bring the economy in for a soft landing after spending billions on stimulus measures to spur growth during the global economic slows. China's fuel price increase will add to 0.07% of a sequential increase in consumer price index in December, the commission said.

Beijing controls fuel prices using a basket of international crude types but has veered from the formula when it might have meant major price increases.

China will raise gasoline and diesel prices by 310 yuan ($46.53) and 300 yuan ($45.02) per metric ton, the commission said. That represents a gasoline price increase of 0.23 yuan per liter, or about 13.1 U.S. cents per gallon. Diesel will rise by 0.26 yuan per liter, or 14.8 cents per gallon. The price applies to what's known as ex-factory production--actual retail prices at the pump vary by region and market.

The commission postponed the increase until now and has also controlled the magnitude of the price increase due to inflation and fuel supply issues, it said without elaboration. It said it expects China's reliance on petroleum imports to be at nearly 55% in 2010.

China will continue to subsidize farmers, the fishery, forestry and public transportation, the commission said. The country won't raise prices of urban and rural public transportation including buses, train and air transport after the price increase, it said.

When China last adjusted fuel prices, on Oct. 26, benchmark New York Mercantile Exchange light, sweet crude futures were around $83 a barrel, compared with just under $90 Tuesday.

As part of it inflation-busting drive, China took a series of measures in November to rein in the prices of agricultural commodities, including price controls and releasing state reserves of some goods.

China's central bank has raised the reserve requirement ratio for banks six times so far this year, with the last three increases coming in the past month. This indicates the government is increasingly concerned about inflation and excess liquidity.
