Unfortunately, with all of the major problems in the world today, the US is too much to blame to be able to solve them. We were seen as a neutral force around much of the world in the post-colonial era (we were a colony who threw off our empire, as much of the world was doing in the 1950s through 1970s -- not coincidentally the apex of American power). But as we've operated the world, we made mistakes, and we're having to deal with those now. Look at all the big problems: global warming (we're the major cause and we're so addicted to oil that it ain't gonna change), Islamist terror (so we inherited the modern conflict through Sykes-Picot, but we escalated it enough that it's our problem now), North Korea (we caused it but China has to live with it), and so on. China is in a MUCH better position to address all of these. Their economy is just now industrializing heavily, and they're doing it with the focus of leading a new global clean energy revolution because they have determined that it is the only way China can obtain widespread prosperity. Sea level rise will hurt China as much as anyone, and their pollution levels are unacceptably high. Their peak industrial scale is 3-5x that of the United States, and their manufacturing capacity will never be challenged given the population difference. They also don't have the baggage that we do in the middle east -- America and the Christian west are collectively referred to as "Crusaders", even by liberal Jews in Israel. In many minds, we're just the latest in an ugly, 1200 year long procession of white people who come in and wage wars of conquest to distract from the problems at home (the early crusades were a way for the European nobility to keep their 3rd and 4th sons occupied / killed lest they cause a succession crisis). Sure, they're mixed up with the Uighirs, but honestly they don't oppress the Uighirs any more than they oppress similar opposition groups. And the key here is that China only does it within their borders. And Korea... yeah, China really doesn't want a small-scale nuclear war happening on its border. Any radioactive fallout would likely destroy China's economy for a decade or more -- considering the engines of China's economic might are mostly on the eastern coast of the country. So China is willing to tolerate almost any level of bad behavior by the Kim family. Best case scenario for North Korea is a power vacuum caused by the death of a Kim where the Chinese military comes in and runs peacekeeping and propaganda with an iron fist. Very few countries know how to urbanize farmland filled with illiterate farmers. China is one of them.
