This may come as a surprise to people, but most of the rice that is being supplied to various parts of the world come from China. There are about 193 million metric tons of rice that are being produced and distributed to various parts of the world. This is far bigger than what other countries are producing.
A lot of the rice producers also come from Asia, probably because rice is considered to be very important to Asian countries. Most people who live in Asia cannot imagine eating a lot of food without rice. If you travel to Asia, expect that there will be days when you would see a lot of rice meals.
