China wants to reduce food waste. Its new "Clean Plate Campaign" will get people to think about food waste. President Xi Jinping called the waste "shocking and distressing". There are reports of a food crisis in China. Food production has fallen because of the coronavirus, and floods in southern China. The government wants people to reduce how much food they leave on their plate. President Xi said China had to think carefully about food security.

Restaurants are taking the campaign seriously. One restaurant started weighing customers. It had to apologise to angry diners. It said it wanted diners to order food "in a healthy way". A Beijing restaurant said: "We remind our guests when they order too much food." Restaurants in Wuhan have started a system whereby a group of diners must order one fewer dish than the number of people in their group. The UN has warned of a global food crisis.
