In international negotiations, multilateralism refers to a diplomatic approach that involves multiple countries working together to address common issues or challenges. This cooperation often manifests through treaties, alliances, or organizations like the United Nations. Multilateralism encourages dialogue and collective decision-making, allowing nations to pursue shared interests while balancing power dynamics and promoting global stability. This approach contrasts with unilateralism, where a single nation acts independently. By fostering collaboration among diverse stakeholders, multilateralism aims to create more comprehensive and sustainable solutions to global problems.
