To clarify a point about the size of the U.S. economy and its importance in the world, China imported 12% of global metals consumed in 2000. Now it imports up to 47% a year. China's growth has a major impact on emerging economies. The U.S. has no impact because it is a service economy. China has gone from sending less than a million travelers overseas in the mid-1980s to 100 million now. You hardly see American tourists in Asia any more.
