Take away China from BRICS and what do you have? Yes, the US dominates the Western club but the disparity between the EU and the US is not as huge as between China and the other countries. China does not seem to like getting entangled into alliances, which is probably prudent. But it also means that there won't be a "BRICS NATO" type of organisation either.BRICS is rather interesting because it appears to be heading down the path of the self-fulfilling prophecy. In practice, it’s little more than a flashy name and a social club for government leaders to meet at all those annual conferences, with little tangible impact to show for it.
And there isn't even a common financial architecture. The Indians and Brazilians have both said no and China itself seems hesitant to open up its capital account fully. China has almost fully caught up with the West technologically and in some areas went ahead of the West. But in terms of financial prowess, there is still very little competition for the US-backed financial system. And it's not clear to me that China even wants to change that, because the price paid would be loss of financial sovereignty.
The US govt cannot intervene to make the dollar cheaper, despite what Trump says, because its capital account must stay open: a precondition for having the world's reserve currency. China has so far not been willing to accept that, and without China, the entire project to replace the dollar collapses. So until China changes its mind, I will remain a BRICS skeptic.
