BRICS expansion to bolster Global South influence

Greater alignment

Khan said he does not see such lack of cohesion as an issue, and that instead over time there will be greater alignment. The unity of the grouping will depend on its flexibility, openness and creating its own internal organic cohesion, he said.

"One ... attractiveness of the grouping is having diversification of opinion, but overall you know the ship is sailing to a particular place. But on the way it could take different types of diversions.

"Who would have thought, for example, that Saudi Arabia and Iran could find alignment? But look at what is happening since the Chinese-brokered peace deal (between the two sides in March). We have had this alignment take shape and form. It's truly remarkable."

Adhere said that despite possible problems that pit individual member states against one another, countries speak in a consensus fashion when it comes to BRICS' decision-making.

"We hope as more countries join, the primary drive to deliver development for their people will override the seemingly small tensions that may appear between countries."

Delivery of the desires of the joining members is the biggest tool that the BRICS countries have to build coherence, relevance and sustainability, he said. This is in addition to ensuring that members do not face the kind of traditional problems that they faced with Global North partners.
