BEIJING - China's government said on Friday it will raise its minimum purchase price for wheat and rice and expand corn planting areas this year, reiterating earlier plans to boost grain output after prices soared last year.

The moves, outlined by Premier Li Keqiang and the state economic planning agency in annual reports to parliament, also come after the COVID-19 pandemic last year fuelled food security jitters in the world's most populous country. 

"Ensuring that our people have enough food remains a top priority for our government. We are resolved to ensure food security for our 1.4 billion people, and we know we can achieve this," said Li in his 2021 work report.

China buys wheat and rice, its staple food grains, from farmers at a minimum price when the market price drops below that level to support food production.

It had cut those support prices in 2018 after stocks of the grains ballooned. However, this year it lifted the minimum price for wheat for the first time since 2014 amid its renewed focus on food security.

Surging corn prices have also pushed animal feed mills to use more wheat, tightening supplies of the grain.

Recognising the competition for land between soybeans and corn, the state planner prioritised higher corn acreage and said production of soybeans would be stable this year, changing prior years' trends of large increases in output. It also said it would support production of grains on barren land.

China will also work to conserve fertile black soil in the northeast while adding more high quality farmland, said Li.

The country will ensure stable supplies and prices of farm products, he added. The Ministry of Finance said spending on stockpiling of grain and edible oils would remain the same as last year at 122.5 billion yuan ($18.92 billion).

The state planner highlighted the need to continue to rebuild and stabilise hog production, and to develop cattle and sheep sectors.

China needs to ensure the security of animal and plant breeding resources in the five years to 2025, added Li, but no specific targets were set for commercialisation of genetically modified crops.
