The problem is China will never open up her capital markets (and for a good reason) and alow her curency to be freely traded, so the RMB will never be a major world reserve currency like the dollar or even the Euro/pound. I don't think Chinese leaders want that either. They just want or need to keep enough presence for RMB to negate any US nuclear option sanction moves against China like cutting china off swift/dollar . So China needs some.sort of alternative and option. However that doesn't means opening up her capital markets , and even more so to have a resevre cureency it has to be extremely liquid and very, very easy to convert into and out of it, something that won't be possible with the RMB for obvious reasons..So people should stop this thing of BRICS or whoever replacing the dollar . Won't happen for obvious reasons.
