BRICS leaders agreed to establish an integrated early warning system for infectious diseases as the expanded bloc sought stronger cooperation across the Global South amid rising geopolitical tensions, climate disasters and supply-chain disruptions. Indian Prime Minister Narendra Modi, speaking on the second day of the summit in New Delhi, warned that the weaponization of technology and critical minerals could hinder global development and shared prosperity. The group’s joint declaration called for dialogue to address conflicts, a multipolar world order, reforms to the United Nations and global financial institutions, and opposition to unilateral sanctions and trade barriers. BRICS also backed greater use of local currencies, stronger cross-border payment systems, and cooperation on food security, energy, digital infrastructure, artificial intelligence and climate action. Modi urged members to turn summit agreements into time-bound results and said China would take over the BRICS chair for the next term.
