Food supply & security are essential, that has been

focused by China governments for thousands of years. In new China, grain production has been increased to level of annual 600 million tons since 2010 that is adequate for the basic demand of 1.4 billion Chinese people and per capita grain consumption is above the average of the world.

China has ability to produce plenty of food for Chinese people. No doubt. Period!
