As the world's most populous nation, China has the most mouths to feed. In 2022, its population reached 1.41 billion – roughly a sixth of the world's 7.9 billion people. Yuan Longping, known as the "father of hybrid rice," once told CGTN, "A tiny grain could either save a country or bring it down. The importance of food security should never be underestimated."
