Current studies on China's food security are largely based on the perspective of grain self-sufficiency, and discuss whether China can feed itself at the national level through its grain production. As a result, the Chinese grain self-sufficiency policy of maintaining a self-sufficiency rate of above 95% tends to be regarded as a benchmark for evaluating China's food security status. Accordingly, China's grain demand will be largely supported by Chinese-owned farmlands both locally and overseas, resulting in a new scenario for China's grain policy, that of being self-supporting. This paper argues that China's adjustment in terms of its food security policy not only further secures its grain supply, but also influences international norms. An important finding of this paper is China's reliance on government-supported companies and bilateral agreements, not only to safeguard production stemming from investments, but also to influence the regional food security status.
