Number: RS21344 Title: European Union Enlargement Authors: Kristin Archick, Foreign Affairs, Defense, and Trade Division Abstract: On January 1, 2007, Bulgaria and Romania joined the EU, enlarging the Union to 27 countries. The EU's previous enlargement in May 2004 brought in Cyprus, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia, and Slovenia. In 2005, the EU agreed to open accession negotiations with Turkey and Croatia, and named Macedonia as an official EU candidate; in December 2006, the EU partially suspended talks with Turkey over ongoing disputes over Cyprus. Although the EU maintains that the enlargement door remains open, "enlargement fatigue" has become a serious issue in Europe and some experts believe that EU enlargement may be reaching its limits. The status of EU enlargement is one of many transatlantic issues likely to be of interest to the second session of the 110th Congress. Pages: 6 Date: July 3, 2008
