I bet China will keep exporting rice to 亚非拉 at low price.
1. China has more than 50% of 粮食 storage of the world now. 2. 玉米和大豆 are also 粮食, especially for Northeast villagers.
中国每年还要进口粮食 is because China 人多地少，实现粮食自给自足的资源成本和经济成本太高，进一步增产粮食的边际成本高昂. but now the situation is different. the rice price has been doubled and still going up.
对所有质疑中国的人只需一句话来回答。“deal with it！”。
