So, they are reliant upon imported food. They are also 80% reliant upon imported oil, which can be blocked easily at any one of several different choke points along the way from where it is pumped until it gets to China.

Iron ore
The Chinese steel industry is not only dependent on the global market for sales, but also on the supply of raw materials, especially iron ore. Although China domestically mines large quantities of iron ore and possesses the fourth largest reserves of iron ore in the world, its iron ore is of low quality and contains only relatively low quantities of iron. Therefore, China is heavily reliant on the global iron ore supply, being by way the largest importer of iron ore worldwide. Imports are coming mainly from Australia and Brazil, these two countries together making up more than 80 percent of total iron ore imports to China.
