Uhm, what do you mean here? In what way did the US "stall Chinese growth“ in any meaningful sense?
Sanctions?
Or the fact that the US's own poor economy is stalling world growth in general, and also slowed down Chinese economic growth?
If you are talking about the former, you should know that those doesn't matter as much as the media wants you to believe.
If you are talking about the latter, you really need to stop taking things out of context. Stalling Chinese economic growth, in the face of stalling global growth, as a result of a weak and on-the-brink-of-recession US economy, propped up temporarily by unlimited printing of dollars? Those are NOT real indicators of any kind of "stalling Chinese economic growth". In fact, it would be a good thing for China, because it is helping China to get rid of systematic economic/financial risks.
The fact that the Chinese stock market has pretty much been artificially kept at a relatively low point in the last decade, is ONLY good and nothing bad for China. It might make it look weak on growth on paper, but it is preventing strategic and systematic economic/financial risks. Imagine if the Chinese stock market is allowed by the Chinese government to bubble up to the 10k to 20k index point, it will be a juicy harvest for the US financial vultures. And this juicy harvest would have made China into the the next Japan.
Any one who know how capitalism works, would look at that high US stock market and recognize how big of a bubble it is. It is a bubble waiting to burst, and it should have burst a few years ago already, in order to keep the long term capitalist economy safe and healthy. Recession is a natural periodic occurrence to the capitalism economies, and it is NOT a bad thing systematically. Preventing it to happen, delaying its happening, is BAD for the capitalist economy, systematically. This will ONLY result in greater long term problem and even total collapse.
