Greetings, the currency of Saudi Arabia is the Saudi Riyal which has a value of 0.27 cents of a dollar, the proposal of this country is to pay Russia in its currency Rubles, this would make for the first time an international oil trade outside the dollar. It is very true that the Yuan is so far the only currency that is competing with the dollar, but that does not mean that the dollar should be the only currency with which these operations are carried out.
