This is not entirely accurate, but you are right that they haven't developed to that stage yet of invading countries on the other side of the world, but if the power level gets high enough that's exactly what will happen. USA was also where China is at now and it took a while to get to that point. China has its own version of some of the things you mentioned, and some other things that are not pleasant. Your optimism that China will be a better hegemon than past ones in history is sadly naive.
