Don't count the Chinese out when ever they have been side lined they have copied then innovated and gotten ahead. Now their economy in real terms is actually bigger than the US economy and more well rounded so sanctions or any kind of restrictions boost their local companies by removing any competition.

And looking at how the recent wars and skirmishes in Ukraine, Israel and Pakistan/India have gone I think western military superiority is no longer real. In a conventional war of today US will lose and most likely nuke the other country so I think its best for the world if China gets so powerful that USA accepts that it no longer is the sole super power and we can avoid a nuclear war. As that is where we are heading either a multi polar world or a nuclear holocaust.
