China will promote inclusive sharing to ensure that the benefits of innovation in food security are shared more widely and fairly among Asia-Pacific economies and their people, according to the National Food and Strategic Reserves Administration.
Liu Huanxin, head of the administration, put forward proposals on food security, a shared concern among Asia-Pacific economies, at the APEC high-level public-private dialogue on food security on Thursday.
Stressing the importance of digital empowerment, he said China will promote the large-scale application of innovation across the food supply chain and expand the use of artificial intelligence, digital technologies and smart processing across this sector.
He also called for closer cooperation among government departments, businesses, research institutions and international organizations to promote open and mutually beneficial cooperation in food security.
During the 14th Five-Year Plan period (2021-2025), China kept its domestic grain market broadly stable and deepened international cooperation in the food sector, contributing to food security across the Asia-Pacific and beyond, the official noted.
Over the next five years, China will continue to enhance its overall food production capacity and strengthen its ability to safeguard national food security, he said.
The dialogue, held in the coastal city of Dalian in northeast China's Liaoning Province on Thursday, drew nearly 150 representatives from government departments, business associations, research institutions and international organizations of APEC economies.
