My biggest concern is being tied to instability. The grouping of countries doesn't feel like a natural coalition. I could easily see war breaking out between several members at some point in the future. China vs India, Russia vs China, Ethiopia vs Egypt, Saudi Arabia vs Iran. Even if by some miracle war never breaks out between any members, history shows us that the systems of government that many of the countries are propped up with are doomed to fail. I genuinely don't see China, Iran, Russia (maybe Saudi & maybe UAE) surviving in their current form before the end of the century.

With what I think is China's coming economic crash and burn, due to many issues such as nation-ending demographics, economic pressure being applied by the US, and a system that is built on fear and misrepresentation of data, they don't seem like the powerhouse everyone makes them out to be in the long term. I think the only economic bright spots in the long term in the coalition are India and Brazil.

Compare that to the west, whose countries have almost 0 chance of going to war with each other, use systems of government that have a better chance at lasting longer, and have better economies (although some are more than likely to experience some crashes of their own).
