I don't think you're looking at this objectively. Almost every country on Earth has worse monetary policy than the US. There is no contender for global reserve currency. There is absolutely no other currency that can be used in any prectical way. The Chinese can be interested in whatever they want, but no one wants yuan, and probably no one ever will. Chinese monetary policy is not only bad, but it's opaque and unpredictable, and that is precisely why no one wants their currency. It's not even freely convert able, so it's ot of any use to anyone outside China. And it never will be freely convertable, because every time they try it, it results in massive capital flight. Add to that the fact that China is in demographic and economic decline, and I would be surprised if the yuan even exists in 20 years.
