American exceptionalism is missionary. It holds that the United States has an obligation to spread its values to every part of the world. China's exceptionalism is cultural. China does not proselytize; it does not claim that its contemporary institutions are relevant outside China. But it is the heir of the Middle Kingdom tradition, which formally graded all other states as various levels of tributaries based on their approximation to Chinese cultural and political forms; in other words, a kind of cultural universality.
