Corn won't be used for bio-fuel in 5 yrs

China will shift its dependence from corn to sorghum, cassava and sweet potato plants to make bio-fuel in the next five years.

Part of the government's efforts to develop bio-fuel without harming general food supply and security, the shift will ensure a healthy supply of corn both as food and fodder.

Cassava and sweet potato both are high-yield plants, and though edible, they are not used as staple food. So their use as raw material, as opposed to that of corn, won't create any artificial shortage of food products.
