     BEIJING, Feb. 10 (Xinhua) -China's economic planning agency Thursday announced a rise in

minimum rice purchase prices this year to encourage farmers to grow more grain.

     A statement on the National Development and Reform Commission (NDRC) website said the

government would continue the policy of minimum purchase prices in major rice-growing regions in

2011.

     The rises in the minimum rice purchase price had been approved by the State Council, China's

Cabinet, said the statement. 

     The purchase prices for japonica rice will rise 21.9 percent to 128 yuan (19.4 U.S. dollars) per

50 kilograms, while prices for early and middle-late rice will increase 9.7 percent and 10.3 percent to

102 yuan and 107 yuan per 50 kg respectively.

     Rice and wheat are two major grain crops in China.

     The State Council pledged Wednesday to step up efforts to boost grain production as drought

continues to wreak havoc in north China's wheat growing regions.

     China's main wheat-growing regions, including Shandong, Henan, Hebei, Anhui, Shanxi, Shaanxi,

Gansu and Jiangsu provinces, have been plagued by drought since October last year.

     Drought has affected about 7.73 million hectares, or 42.4 percent, of the total winter wheat crop

area in the country's eight key producing provinces, the Ministry of Agriculture said Wednesday.

     China's grain output rose 2.9 percent last year to 546.41 million tons, marking the seventh

consecutive year of growth.
