With all the complaining about China we need to remember that it was Nixon who opened China to the world economy.
Russia has more nukes but US has more precise and powerful nukes. It really doesn't matter though because either country can kill every living thing on earth. Therefore neither country will use them knowing retaliation is swift.
As for China invading Taiwan that will not happen and while China has more troops the US has the better weapons. I think China doesn't want a war with the US.
