The European Union (EU) fosters collaboration among its member states through various institutions and policies.
Key institutions include: * The European Commission, which drafts legislation, implements policies, and enforces EU law. * The European Parliament, a legislative body with supervisory roles that is directly elected by EU citizens. * The Council of the European Union, a legislative body that represents member states.
The EU facilitates the free movement of goods, services, capital, and labor within its borders. It also has a common agricultural policy and a common external trade policy. The European Court of Justice ensures that EU law is uniformly interpreted and applied across all member states.
