Intergovernmental organizations (IGOs) are significant as they facilitate cooperation among member states on various global issues, such as trade, security, and health. These organizations, including the United Nations and the European Union, provide a platform for dialogue, negotiation, and collective decision-making, enhancing multilateralism. They often play crucial roles in conflict resolution, humanitarian aid, and sustainable development. By pooling resources and expertise, IGOs address challenges that individual nations cannot tackle alone. Their significance lies in promoting peace, stability, and prosperity on a global scale.
