World leaders have gathered in Rio de Janeiro for the annual G20 summit, where host President Luiz Inácio Lula da Silva is pushing for a global alliance against hunger and poverty. The two-day meeting arrives at a critical juncture for international diplomacy, as delegates attempt to navigate deep divisions over the conflicts in Ukraine and Gaza. While Brazil aims to focus the agenda on social inclusion and sustainable development, discussions are being shadowed by the shifting political landscape in the United States and stalled progress at the concurrent COP29 climate talks in Baku. Early reports indicate that while a consensus on taxing the world's wealthiest individuals is being sought, reaching a unanimous joint statement on security issues remains a significant challenge for the group's negotiators.
