World leaders have gathered in Rio de Janeiro for the annual G20 summit, with Brazilian President Luiz Inácio Lula da Silva launching a flagship Global Alliance Against Hunger and Poverty. The initiative has already secured backing from over 80 countries, aiming to accelerate efforts toward food security and poverty reduction. However, the summit faces significant hurdles as delegates attempt to reach a consensus on climate change financing and the ongoing conflicts in Ukraine and the Middle East. While host nation Brazil seeks to prioritize the concerns of the Global South, discussions remain complicated by shifting political dynamics in the United States and differing views on international trade policies. Analysts suggest the final communique will serve as a critical indicator of the state of multilateral cooperation in an increasingly polarized global landscape.
