In line with its traditional Western orientation, relations with Europe have always been a central part of Turkish foreign policy. Turkey became one of the early members of the Council of Europe in 1950, applied for associate membership of the EEC (predecessor of the European Union) in 1959 and became an associate member in 1963. After decades of political negotiations, Turkey applied for full membership of the EEC in 1987, became an associate member of the Western European Union in 1992, joined the EU Customs Union in 1995 and has been in formal accession negotiations with the EU since 2005. Turkey's support for Northern Cyprus in the Cyprus dispute complicates Turkey's relations with the EU and remains a major stumbling block to the country's EU accession bid.
