China is real important in this but we already know a lot of interests would be in favor of a gold-backed rest.  Basically it's everyone who is getting screwed by the Fed-Euro bankers. That would be US (Trump and the people), Russia, the Saudis,   and rthe BRICS really although as you say China is unknown...but they have been going crazy for a few years buying gold so I think they would like it.   Also South Africa.
