My controversial 2 cents, which might be very wrong: There is a major difference between the two countries: China sees itself as a single "people", in the sense that there is a clear dominating national identity linked to a certain culture and ethnicity, similar to other old world countries in the past century (some of which are still like that). The US in this sense is closer to other "new world" countries, with a national identity not clearly tied to an ethnicity. Sure, there are groups who try to make the US a more homogeneous country (and not by intermixing to oblivion), but the US identity is largely multi-cultural and multi-ethnic. So the Chinese who move to the US eventually become Americans, but Americans who move to China will never become Chinese. For China there's no cultural assimilation, no integration, no coexistence. There's not even "separate but equal", because there's no "equal".
