extension

There are currently five official candidate countries. These are Turkey, Serbia, North Macedonia, Montenegro and Albania. The EU grants this status to states whose application for membership has been unanimously accepted by the Council of the European Union. There are also two other potential accession countries: Bosnia and Herzegovina and Kosovo.

Membership requirements

In order to become a member of the European Union, the candidate country must meet a number of requirements, the so-called Copenhagen criteria. The European Council set it in 1993 at a meeting in Copenhagen. They were confirmed in 1995. Every applicant country must meet these criteria. The EU supports the candidate country in the gradual implementation by providing the framework and the necessary instruments with pre-accession strategies and accession negotiations.

  • Political criterion: institutional stability as a guarantee for a democratic and constitutional order, for the protection of human rights and the respect and protection of minorities
  • Economic criterion: functioning market economy and ability to withstand competitive pressures and market forces within the Union
  • Acquis criterion: ability to assume the obligations arising from membership and to adopt the objectives of political union and economic and monetary union (adoption of the "acquis communautaire", i.e. the acquis communautaire)

In order for the European Council to decide to open accession negotiations, the political criterion must already be met.
