Diplomacy in Action

Members of EU

The European Union (EU) is one of the United States' strongest strategic partners, with the importance of the relationship reflected in our close cooperation on regional crises and conflicts, our extensive collaboration on a wide range of global challenges, from counter-terrorism to nonproliferation, and our deep trade and investment relations.

In 2004, Cyprus, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia, and Slovenia joined the EU, bringing total membership to 25. Romania and Bulgaria became members in January 2007, which brought the EU's membership total to 27 countries.
