Diplomatic groups are collections of countries or organizations that work together to address common issues and promote peace. These groups often meet to discuss international relations, trade, security, and humanitarian efforts. Examples include the United Nations and the European Union, which facilitate cooperation among member states. These groups can also take the form of alliances or coalitions, where countries collaborate on specific goals. For instance, the North Atlantic Treaty Organization (NATO) focuses on collective defense, while the African Union addresses regional challenges in Africa. Such collaborations help nations navigate complex global issues more effectively.
