What are examples of supranational countries?

Supranational countries refer to entities where member states transcend national borders and delegate authority to a higher authority for mutual benefits. Examples include the European Union (EU), where member countries cooperate on economic and political issues, and the African Union (AU), which focuses on regional integration and development. Other examples include the United Nations (UN) and the World Trade Organization (WTO), which facilitate international cooperation and governance. However, it's important to note that these organizations do not create new countries but rather foster collaboration among existing ones.
