Pork is a staple of the Chinese diet

The benchmark lending rate will rise to 7.47% from 7.29% with effect from Friday, while the main deposit rate will increase to 4.14% from 3.87%.

Chinese inflation hit 6.9% in November, its highest level since 1996.

Separately, Beijing has promised to double subsidies for pig farmers to ensure pork supplies and lower prices.

Soaring food costs, and especially the price of pork which is up 56% in the past year, have been blamed for driving the main inflation rate to an 11-year high in November.

Larger farms

China's pork output fell this summer due to higher feed costs, and after disease led to a livestock cull.

The government has said it will pay farmers a subsidy of 100 yuan ($13; £6.50) for every fertile sow next year.

On Wednesday, the government vowed to spend 2.5bn yuan next year to help farmers build "standardized, large scale" pig farms, the Xinhua News Agency said.

Beijing also decided to extend sow insurance, which was launched in August to cover losses from diseases and natural disasters, to "as many sows as possible".

The government also said it would release part of its corn reserves to the market to reduce food inflation pressure, Xinhua said.

The last interest rate rise was introduced in September.

"Given the background of upward pressure in domestic prices... and in order to guide the public's expectations about inflation, we have put into play price adjustment tools," the central bank said.
