These are good points but I would disagree specifically that other nations want "a more equal world". My take is that they want to wear the crown next, not share it.
BRICs banding together amongst each other to create economic prosperity is the only means for these countries to increase their living standards, and so cooperation is incentivized.
Competition is a zero sum game for these countries, and they know that.
