Huge powers are never your friends - that much is certain. Whatever they do is ultimately meant to further the goals of their own citizens (the wealthy and powerful, of course) - this is true of China, the USA, the USSR, and every other empire in history. Some small countries benefit from an empire's influence, when they happen to be in a place where that empire wants stability (for example, Romania has mostly benefitted from US colonization). Other small countries are devastated and thrown into dictatorship (Nicaragua, Cuba, Iran, Honduras, Guatemala, Vietnam, Yemen, Iraq, Afghanistan, Palestine, Syria, to name a few).
Your selective dismissal of conflict is telling. If you're afraid of, and dislike, the USA then that's unfortunate, but it doesn't leave much more to discuss.
But sure, some misguided folks might prefer the lifetime dictators of Russia and China much better. I'm sure that'll last until a real conflict starts.
