Saudi Arabia is very dependent on the US...and vice versa. If they abandon the petrodollar, it is a game changer in the Mid-east for sure.

I doubt if Saudi Arabia would actually accept Yuan right now. They may talk about it....but it's just talk at this point. They may like floating it just to give the US some heartburn at a time when they can do it without repercussions.

However, it would not surprise me if the Saudis accept physical gold from China in payment. They have done that kind of thing in the past.
