This indicates that in China, the shortage of foodgrains is not because of a bad harvest alone. Much of it is man-made due to greed, as also poor storage. Greed cannot be eradicated and China knows that, but China is moving towards scientific storage, and to that extent, maybe China can ensure the losses are minimal. Food security is an important aspect that will prevent social unrest. It is also an aspect that can cause international chaos. Hence, all nations have to ensure that the loss of foodgrains is minimal. For a populous country like China it is critical!
