You can buy from China though. And China is the largest import trading partner for the majority of countries in the world. They literally don't need to do anything to prop up a "petro-yuan".
You can’t largely. At least not with offshore yuan. To do that you have to go through the controlled settlement channels to get onshore yuan. That’s tightly controlled to protect the peg.
So no one is going to use a controlled currency for a hard liquid commodity. So if China wants petro yuan they have to liberalize that, which will break their peg.
China could have more international trade in the yuan before all of Americas recent misadventures. But that has cast consequences for their economy, and possibly the ruling elites power structures.
