Abstract: Based on the bibliometrics, the study analyzes the research hotspots of global food security and research topics involving keywords related to "China" in depth; at the same time, it summarizes main viewpoints from the international community, existing problems and challenges, as well as corresponding countermeasures and recommendations of food security in China through a full analysis and review on the reports issued by important international organizations, research institutions, think tanks, multinational agricultural enterprises, and authoritative scholars. The study discovers that: The research hotspots of global food security mainly include climate change, sustainable development, nutrition and health; climate change is the most important research topic with the largest amount of relevant literatures. China's food security is highly concerned by the international community. Regarding questions like whether China's food is secure or whether it potentially poses a threat to the world's food security, the international community currently holds a relatively positive view, shifting from the previous negative one. Although China has achieved the security of food in terms of quantity, there are still weaknesses and shortcomings in terms of its nutrition security and environmental sustainability. In the future, China should strengthen the planning and layout in relevant areas to achieve all-round food security as soon as possible. Relevant findings in this study are of great significance and enlightenment to the comprehensive and profound understanding of the current and potential food security problems in China from different perspectives, and can also greatly help respond to the problems and challenges faced by China's food security in a more active and scientific manner.
