Leaders from the world's largest economies have gathered in Rio de Janeiro for the G20 summit, facing a complex agenda focused on global inequality, climate change, and international security. Brazilian President Luiz Inácio Lula da Silva officially launched the Global Alliance Against Hunger and Poverty, a flagship initiative aimed at coordinating international efforts to provide food security for vulnerable populations. The summit arrives at a pivotal moment as participants navigate the transition of power in the United States and the ongoing conflicts in Ukraine and the Middle East. While draft statements indicate a commitment to multilateralism, observers note significant challenges in reaching a consensus on climate finance and trade tariffs. European and South American leaders are also using the forum to discuss the long-delayed Mercosur-EU trade deal, amid varying levels of support from member states. As the summit progresses, the ability of these nations to provide a unified response to global economic instability remains a central focus for international markets.
