Out of pure ignorance. Don’t have time for a complete history lesson here but I watched a short doc on the petroyuan. China is attempting to emulate our petrodollar that has made the us dollar the standard of international business largely due to its perceived stability. China is also propping things up with all their importing and a massive potential consumer population. Due to Trump’s America first/arrogance/isolationism/trade wars, that perceived stability is threatened and other country’s are starting to see China’s offer to switch more tempting, at least partially if not all in. Not Trump’s fault, but our nonstop wars now blatantly just to maintain our dollar value is getting on the world’s opinion nerves. Lastly (or maybe not) with our Oprah style “You get a sanction! You get a sanction! Everybody gets a sanction!” policy, China is more than happy to step in and fill in that needed aid. This won’t happen overnight but I have no doubt our government will deal with it in the worst ways possible. We’re like the global top 1% that’s dominated the world for the past 70 years trying to convince everybody our problems are the most important, which shouldn’t be shocking considering that’s how we deal with our own population.
