Except Saudi Arabia (US vassal), they are all very involved already in Petro and in their own crypto currencies, in many different ways. One of the companies developing Petro is Russian and Venezuela has huge relations with Chinese companies providing hardware (certainly also for their newly launched State owned mining factories, and also for private miners that are now regulated in Venezuela).

What we read here is the US/European focused imperial (and often racist) culture that is losing grip: people repeat narratives from the US propaganda as if everything coming out from Bloomberg, Reuters, CNN, New York Times was true, and anybody else was an idiot or evil. Well, it will be nice to see. Many surprises to come.
