The people are the foundation of a country; food is the primary need of the people. As food decides national prosperity and the people's wellbeing, food security is a major prerequisite for national security. Since the founding of the People's Republic of China (PRC) in 1949, China has always prioritized food security in state governance. Despite a weak agricultural foundation and extreme poverty, the Communist Party of China (CPC) has led an unremitting campaign of hard work over the past 70 years that has made China basically self-sufficient in food supply. China now has enough food to feed its nearly 1.4 billion population, and has remarkably improved the people's nutrition and life quality. China's food security is a success of worldwide significance.
