Most of us have been following developments in biotechnology approval for many years. The most recent issue is the non-approval of certain corn events by China. Viptera (MIR162) corn has not been approved there since its introduction in 2010; Duracade, new this year, is in the same situation. The greatest impact of the Chinese situation is on distillers grains from ethanol production. China is a major importer of dried distillers grains with solubles (DDGS); much less so for whole corn.
