In fact, this issue involves the different basic national conditions of the two countries. For China, although the territory is large enough, the effective planting area is limited, and even with excellent cultivation techniques, it can not meet the requirements of all the population for food crops. On the other hand, if we want to expand the planting area, we need to constantly reclaim wasteland, which will inevitably destroy the ecological environment, and the cost of consuming ecological environment in exchange for increasing grain production is higher than that of imported grain, so it is more cost-effective for us to import grain.
In addition to protecting the ecological environment and pursuing lower resource consumption, imported grain can also play a role in stabilizing social development. Essentially, their grain production can't meet the existing requirements. If they don't import as required, the existing food prices will continue to rise. Everyone needs to pay more money to get food crops, and people's livelihood projects will basically be endangered. Once most of ordinary people's income will be spent on housing, happiness will inevitably decrease and various social phenomena will be exposed one by one.
That being the case, why does India import and export a lot of rice? Although the total area of the host country is less than one third of that of China, the planting area is similar to ours and more important. The cold and humid climate here is especially suitable for planting rice. In my opinion, it can be planted even in three seasons. Coupled with the lack of industrial development in the host country, most of the population is engaged in crop cultivation, and rice production is very rich every year. Although they have to eat food crops, they also need other basic daily necessities, so many farmers have to sell rice for cash.
Looking back at India, because of their religious beliefs, they seldom eat meat or drink alcohol. The consumption of food crops in this respect is particularly small, and some of them can be used for import and export to earn some foreign exchange transactions.
Some people may ask, why don't Indian farmers keep food crops for themselves? As mentioned earlier, many farmers in India are tenants or farm labourers, and their own food crops are not their own.
70% of India's land belongs to individuals, and most of this 70% land is concentrated in the hands of landlords. Big landlords prefer to sell food crops abroad, because Indian civilians simply can't afford food crops. This is why many people in India wander around the poverty line, but many import and export food crops.
