International institutions are organizations formed by multiple countries to address global issues and promote cooperation. They can focus on various areas, such as trade, security, health, and environmental protection. Examples include the United Nations (UN), which works on peace and development, and the World Trade Organization (WTO), which regulates international trade. These institutions provide a platform for dialogue and negotiation, helping countries resolve conflicts and collaborate on common challenges. They often create rules and agreements that member states are expected to follow, fostering stability and predictability in international relations.
