I would caution against attributing altruistic motivations to the actions of nation states. The Spratly Islands are having their ecosystem trashed so the various powers can have a fucking dick measuring contest over imaginary lines on a map. So far a bunch of fishermen have been killed and irreplaceable coral reefs have been destroyed, all in service of building artificial islands for reasons that vary depending on the state actor.

Debt trap diplomacy is a problem with every large power including BRICS, the west is currently the biggest offender because the World Bank and the IMF has the implicit backing of US military power projection. It is easier to strong arm “client states” into onerous loan terms and “free trade zones” when there is the threat of their nation being labeled as “supporting terrorism” and have a carrier battle group off shore within days.

I have no reason to doubt that once that BRICS has the ability to project power, basically whenever China has several modern carrier battle groups, they won’t operate any differently than the west does now. The flag and justification will be different but the global south will continue to be exploited.
