China made a prolific use of oil during its rapid economic growth phase. China is adapting to 3 million missing barrels of oil from Hormuz by drawing down reserves, cutting use of crude oil converted into plastics, and other measures. This is an opportunity for China to reduce the amount of oil it consumes by copying the example of more efficient use of oil per unit of GDP that is seen in the last decade in Germany and Japan. This would be better for China and for the world economy as it adapts to the uncertainty and wars of the last 3 decades of the Middle East. The US could also take the example of Germany and Japan in more efficient use of oil for the same degree of growth.
