Serbia, along with 5 other Western Balkans countries, was identified as a potential candidate for EU membership during the Thessaloniki European Council summit in 2003. In 2008, a European partnership for Serbia was adopted, setting out priorities for the country's membership application, and in 2009 Serbia formally applied. In March 2012 Serbia was granted EU candidate status. In September 2013 a Stabilisation and Association Agreement between the EU and Serbia entered into force.
