Interstate organizations are groups formed by multiple countries to collaborate on common interests and issues. These organizations can focus on various areas, such as trade, security, or environmental protection. Examples include the United Nations and the European Union, which aim to promote peace and cooperation among member states. These organizations often create treaties and agreements that member countries must follow. They provide a platform for dialogue and negotiation, helping to resolve conflicts and address global challenges. By working together, countries can achieve goals that would be difficult to accomplish individually.
