The gradual loss of global fora’s importance will lead to the growing importance of interests-based and regional ones like BRICS and the SCO respectively, among others like January’s Indian-hosted virtual Voice Of Global South Summit. These categories of groups have a much greater chance of actually agreeing on meaningful cooperation that tangibly makes a difference, thus leading to them serving as engines for socio-economic, political, and security developments.
Aren't the BRICS also a global forum?
I think they are the first attempt of what the author calls the Russia-China entente to extend into what Western specialists call the "emerging countries" with India, South Africa and Brazil, apart from all the candidates to join, such as Saudi Arabia, Algeria and Argentina.
For now, however, its problem is a lack of political cohesion in the case of Brazil and a greater real geopolitical and geoeconomic weight in the case of South Africa.
