If China ever got as proportionally large and powerful as the USA that would be outstanding good news. Why?
Because to get there they would have to drop their interventionaist and contrived policies and stick with a completely free-market system in spite of all the rough spots that entails.
And they could not adhere to the marketplace without dropping coercive population measures especially forced abortion.
Nor could they get there by threatening Taiwan, claiming international waters as territorial ones, trying to seize other people's mineral rights, threatening satellites, trying to control computer nets, etc etc etc and so forth.
In short they would be a more completely ethical China. We can all live with that if it comes to pass. George Soros would perish from apolexy. Barack Obama would tell them "you did not do that" and Joe Biden would need a larger team of writers in order to come up with the proper number of gaffes.
