Post GFC the IMF was forced to invite China to join the IMFs exclusive reserve currency board (US, UK, Japan, EU). China has since been the only member of the board that is not both monetarily and militarily subservient to the US. This flips when China reverse engineers the global monetary system via its CBDC and Hong Kong. Hong Kong being the original point of British imposing their monetary hegemony over China. As the Chinese learned then, once monetary hegemony is gained over you it is very difficult to reverse. This is a lesson the west may be about to learn for itself.
