In 2006, China imported 145 million tons of crude oil, accounting for 44% of its consumption of oil. With the rapid growth in vehicle sales in China, consumption of fuel oil for vehicles accounted for 35% of oil consumption in 2006. And demand for fuel oil in China continues to grow at the rate of 15-16% per year. To satisfy domestic demand for vehicle fuel, control its dependence on foreign sources of oil and attempt to moderate fuel costs, China has embarked on a robust effort to ramp up fuel ethanol development.
