China's agriculture and food production has developed dramatically in recent years. China is the world's largest agricultural producer and consumer. With only an estimated 10% of world land resources and 6% of world water resources, China produces 30% of the world's rice, a fifth of the world's corn, a fourth of the world's cotton, an estimated 37% of the world's fruit and vegetables, and half of the world's pork. China has become a significant food exporter and has been a net food exporter for most of the last three decades. Against this background, food safety is an issue of national and international significance.
