China became a net importer of oil in the 90s, and the negative externalities of petroleum production would naturally induce them to focus on demand reduction to alleviate that dependency. They also travel far and wide to drill (just as the U.S. does). Is that "petro-politics", environmentalism, or rational energy policy?
