Chinese President Xi Jinping concluded his brief trip to India on Sunday with an offer to help Brics members develop open-source AI and smart manufacturing.Summit host Prime Minister Narendra Modi, meanwhile, warned against turning technology and critical minerals into economic weapons.Experts said the exchange captured the wider picture of the Brics summit. Two days of diplomacy produced a united front against US tariffs, sanctions and “America first” pressure with a joint declaration, while heads of institutions Washington once dominated sat at a Global South table. Concerns over minerals and technology, however, exposed clear limits to that unity.Speaking on the second day of the summit in New Delhi, Xi identified open-source AI and smart factories as two out of five key initiatives to promote economic growth and technological development in the Global South.He also said Beijing would offer to train young talent from other member states in advanced technology and innovation, according to state news agency Xinhua.The bloc has grown rapidly in recent years and is being increasingly seen as one of the strongest voices for the Global South, as the United States becomes increasingly assertive on the world stage.
