Multilateral organizations are groups formed by three or more countries to address common issues and promote cooperation. These organizations often focus on global challenges such as trade, health, environment, and security. Examples include the United Nations (UN), the World Trade Organization (WTO), and the North Atlantic Treaty Organization (NATO). These organizations facilitate dialogue and collaboration among member states, allowing them to work together on policies and initiatives. By pooling resources and expertise, multilateral organizations aim to achieve collective goals that benefit all members, fostering peace, stability, and development on a global scale.
