World leaders have gathered in Rio de Janeiro for the annual G20 summit, where host nation Brazil is pushing for a landmark global alliance against hunger and poverty. President Luiz Inácio Lula da Silva opened the session by emphasizing the need for systemic reform to address social inequality and the escalating climate crisis. The summit arrives at a period of significant geopolitical transition, with discussions expected to cover international trade stability and financing for the green energy transition in developing economies. While many member nations have expressed support for the social initiatives, analysts suggest that reaching a consensus on specific climate funding targets may prove challenging. The meeting also provides a platform for high-level diplomatic discussions regarding ongoing global conflicts and the future of multilateral cooperation.
