Why does China need to import food from abroad for a bumper harvest every year?

To put it simply, there are three main uses of imported grain in China: first, to extract oil, mainly soybeans, second, to feed, such as corn, and third, to supplement food rations to meet diversification, such as Thai fragrant rice and specialty wheat. In fact, rations are rarely imported, mainly to meet different needs. On the whole, soybeans are the most imported, followed by wheat, which is versatile and used to extract oil.
