MOre disproven propaganda.
Computer controlled injection completely eliminates the need for any oxygenation in fuel. So in fact there is a net gain in co2 from production of ethanol.
The problem in China is #$%$ fuel standards in production.
As ethanol is 50%+ more expensive in China there is no chance it will be blended in. Methanol on the other hand is cheaper than gasoline so is blended in today. Very successful.
