Multilateral institutions are organizations formed by three or more countries to address common challenges and promote cooperation on global issues. Examples include the United Nations, World Trade Organization, and International Monetary Fund. These institutions facilitate dialogue, provide resources, and help establish international norms and agreements. These organizations often focus on areas such as economic development, human rights, and environmental protection. By working together, member countries can tackle problems that transcend national borders, such as climate change, trade disputes, and public health crises, fostering a more stable and cooperative international community.
