Dear Louis, I would like to add to this very good article that it seems there is a diminishing amount of arable land in China. The many new infrastructure projects and increasing urbanization takes away arable agriculture land. If this is correct then there is not only a raising demand for foods but also a diminishing internal supply of the main factor of food production. If China still needs to urbanize 10 to 15 % of its population then it housing and infrastructure capacity is still underdeveloped. Therefore we will see less and less arable land in use. Not good long or medium term.
