I agree on this. They buy a lot from China and it can be good for them, for Russia as well. 




Brazil buys stuff from China, so they have demand for Yuan. I don't mean that they would agree to requiring everyone else to pay with Yuan, just that they would allow the Chinese to do so.

Undisciplined

Why do you think Brazil would agree? I think only Russia would support it. India is not gonna accept it and instead India would say we will launch a petrorupee! 😜
