The key to understanding the Americans and world power after 1945 is that maintaining her competitive advantage has always been her key political concern.

Only after the Chinese treasury was replete with US dollars, and after they began to accommodate American and other western global companies, could they begin to develop a global policy. This was part of the story; the other vital aspect was the lesson they learned from the Soviet collapse in 1991.
