Leaders of the world’s largest economies have convened in Rio de Janeiro for the annual G20 summit, marked by high-stakes discussions on global poverty and climate change. Brazilian President Luiz Inácio Lula da Silva officially launched a Global Alliance Against Hunger and Poverty, securing commitments from dozens of nations to address food insecurity. However, the summit faces significant hurdles as diplomats struggle to reach a consensus on the financing of climate transitions and language regarding the conflicts in Ukraine and the Middle East. While some member states push for more aggressive wealth redistribution and environmental goals, others remain cautious, citing domestic economic constraints and shifting political landscapes. The meetings occur against the backdrop of a pending transition in U.S. leadership, which observers suggest could influence future international cooperation on trade and environmental policy.
