I remember alot of stamping, puffing and defiant peacocking when it was strongly asserted that BRICS would not be a serious if not dangerous threat to the dollar's financial hegemony. That would and could never happen you see because they rest of the world are financial amateurs and hacks with no trustable currency and India would never join. And because 'Murica!
And a year later here we are. China seems to be playing the long game now, and backed off it's desire for control and instant power gratification. A year later and now India is part of the mix, which as greatly upped the economic and monetary power of the group.
Ignore at your own financial peril.
