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? But it is time to stop thinking that the two countries come from different planets and that the tensions between them are the product of their differences. 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.
The U.S.-Chinese relationship stands in stark contrast to the one between the United States and the Soviet Union, the last country to rival American power. During the Cold War, when geopolitics was above all a clash of ideologies, increasing contact and growing convergence between the two disconnected societies fostered détente.
But the contemporary era of international interdependence has reversed that dynamic. Today, competition has more to do with status than ideology. As a result, differences between great powers frequently lead to complementarity and cooperation, whereas convergence is often at the root of conflict. As they rebalance their economies and recalibrate their foreign policies, Beijing and Washington are increasingly fighting over shared interests. And as Sigmund Freud could have predicted, the more similar China and the United States become, the less they like each other. Freud called this “the narcissism of small differences”: the tendency of essentially similar people to fixate on minor distinctions between themselves in order to justify hostile feelings. Of course, the two countries are hardly identical. But the chasm that divided them a generation ago has narrowed, and as they converge they are becoming more conflict-prone.
When U.S. President Barack Obama came to power in 2009, he hoped to integrate China into global institutions and encourage it to identify its interests with the preservation of the postwar, Western-led
