World leaders have gathered in Rio de Janeiro for the annual G20 summit, where host President Luiz Inácio Lula da Silva is launching a global alliance against hunger and poverty. The two-day meeting occurs against a backdrop of significant geopolitical uncertainty, including the ongoing conflicts in Ukraine and the Middle East, and the transition of power in the United States. While the Brazilian presidency aims to steer the conversation toward sustainable development and the taxation of the ultra-wealthy, delegates report deep divisions regarding climate finance and international security. Supporters of the summit's agenda highlight the importance of multilateral cooperation in addressing global inequality. Conversely, some analysts express skepticism about the group's ability to reach a unified stance on trade and security, given the rising trend of protectionist policies among several member nations.
