I mean, it was bound to happen. America is by far the HIGHEST energy consumer per capita, and yet we PRODUCE very little.
China actually makes stuff out of the "Energy" they buy.
And RMB, functionally, 20 years ago, what could you buy with it, not much. But today, you can buy fleets of electric busses/ cars/ drones/ drone attack subs/ hypersonic missiles/ RPG/ guided bombs/ drone strike carriers/ 5G networking infrastructure/ Totalitarian Skynet facial recognition camera systems/ Everything a budding dictator needs.
So, I mean, why wouldn't you trade for RMB??
