Since the 18th CPC National Congress, China has put forward the overall food security goal of "keeping the Chinese people's bowl firmly in their own hands" in the new era. The central leadership has introduced a food security policy of "ensuring basic self-sufficiency of grain and absolute security of staple food". The Chinese government has established a national strategy on food security featuring self-sufficiency based on domestic grain production, guaranteed food production capacity, moderate imports, and technological support. This paper summarized the consistency of food security thought in the new era and the integrated national security concept in entirety, representing the people and epochal nature. It is also summarized the successful practice of realizing food security in China under the guidance of the integrated national security concept and the new era food security thought in five aspects: systematic construction, legal guarantee, professional coordination, science technology-based surport and normalization of food saving. In the domestic, the above achievements have a positive impact on the maintenance of core interests, balancing development and security, as well as the upgrading of food industry, triggering the vigor of agricultural modernization. In the globe, Chinese food security is of great significance to the realization of the UN 2030 Sustainable Development Goals. In the new era, China has also made important contributions to stabilizing world food security and global food governance, which could be an important force in global food governance. With the Communist Party of China's 20th National Congress putting forward higher requirements for food security in a broad sense, the connotation of food security in China will be further deepened in the future.
