China will offer more policy and fiscal assistance to its 13 main grain production regions to further ensure its grain security over the next several years, a national agricultural official said on Friday.

Vice Agriculture Minister Yu Xinrong said the country will launch pilot programs to restore black soil farmland in the northeast region and improve cultivation methods in the dry land of the northwest provinces and autonomous regions this year, as well as designing a national standard for minimum water use in various farming activities to save the country's already limited agricultural resources.

The 13 main grain production regions including Heilongjiang, Jilin, Jiangxi and Hunan provinces, contribute 45 percent of China's total grain output and 80 percent of commodity grain. They will gain more technical and fiscal assistance from the Ministry of Agriculture over the next several years.

China's grain output expanded 0.9 percent in 2014 to 607 million tons, the 11th annual increase in a row.
