Many fear that in the not-too-distant future, the world will be torn apart as the gulf that separates China and the United States grows ever wider. How, they ask, can a communist dictatorship and a capitalist democracy bridge the gap between them?

In fact, until relatively recently, China and the United States got along quite well -- precisely because their interests and attributes differed. Today, it is their increasing similarities, not their differences, that are driving the two countries apart.
