World leaders have gathered in Rio de Janeiro for the annual G20 summit, where host nation Brazil has prioritized the launch of a global alliance to combat hunger and poverty. President Luiz Inácio Lula da Silva opened the proceedings by securing commitments from over 80 countries to support a new initiative aimed at redistributing resources to the world's most vulnerable populations. Despite the focus on social issues, the summit is being held under a shadow of geopolitical tension, with leaders divided over the ongoing conflicts in Ukraine and the Middle East. Diplomatic observers note that discussions are also heavily influenced by the prospect of shifting U.S. trade and climate policies following the recent presidential election. While Brazil is pushing for a consensus on taxing the ultra-wealthy to fund climate action, delegates suggest that reaching a unanimous final declaration remains a significant challenge amid fragmented international relations.
