I believe the sudden dollar articles are showing up because of the Russian war and sanctions and a weaker us dollar. Even if the demographics changes play out the issue is the growing economies are consuming out of investment and not capital, and do not run trade deficits (so the other party doesn't have Yuan saved up for example). So there is nothing to reinvest. Almost every country China trades with has a trade surplus with China. Which means everyone is buying from China and they don't save up Yuan, but save up the other countries currency.
