You're saying given a larger playing field, they would forgo it. Let someone else project?

Turkey isn't a great example either due to its NATO membership; their geopolitical motivations aren't that easy to pin down.
And yes, China acts very territorial towards Taiwan and the regional oceans. Taiwan and the surrounding ocean is the one exception to my statement; given the opportunity they'd take it without hesitation.
But for all those countries you listed, I really believe they would remain strong regional powers and not try to dominate the world the way the US does. Shocking as it may be to some of us in the British/American sphere of influence, most countries do not have imperial ambitions, and our opinions of places like China are heavily influenced by the military-industrial-media complex seeking to gin up resentment against foreign powers who don't bow to Western economic influence. (Much criticism of China is valid; that's beside this discussion specifically about imperialism).
So, if they had the resources the US has, I very strongly suspect they would be more muscularly assertive than we are when it comes to world affairs --as I pointed, out, even at their reduced size and power, they desire quite a bit.
Also, correction, China is not only rattling sabers with Taiwan, but Philippines, Vietnam, Japan too.
In other words, yes, if China had the resources of the US it would be a global empire... because in order to have the resources the US has, you need to be a global empire.
This is just a pet theory at this point, I'm not an actual historian.
