But you are asking the Chinese to back such currency and essentially give the other country in BRICS or whoever is going to join that basket an inroad to dictate Chinese Monetary Policy........
Again, the economic might of China is probably multiple time of rest of BRICS put together, hence why China would accept a 1 country 1 vote system and allow country like South Africa to dictate term wrt Monetary Policy China is going to be involved with?
I don't know if you aware this is a very, VERY big ask for China to give up their own advantage on policy making to get into a 1 country 1 vote system where everyone have the same. I mean it would work if you were South Africa or India or Brazil or Russia because you can dictate term on the token currency which is going to be pegged to individual currencies. But this is everything to lose for China to basically see "eye-to-eye" on their monetary policy for the rest of BRICS.
Essentially it's everything to play for the rest of BRICS, and nothing is being bring to the table for China, and you are expecting the Chinese would be okay with this?? It's like you are asking the US to drop the world dominance and accept a 1 nation 1 vote system on SDR Basket.....
