Enlargement is the process whereby countries join the European Union.
How does EU enlargement work?
Any European country which respects the EU values referred to in the Treaty of the European Union (TEU) and is committed to promoting them can apply to become a member of the EU.
The first step is for the country to meet the accession criteria. These criteria were defined at a European Council meeting in Copenhagen in 1993, and often referred to as the 'Copenhagen criteria'.
The Copenhagen criteria set a number of democratic, economic and political conditions for countries who want to join the EU:
- stable institutions guaranteeing democracy, the rule of law, human rights and respect for and protection of minorities
- a functioning market economy and the capacity to cope with competition and market forces in the EU
- the ability to take on and effectively implement the obligations of membership, including adherence to the aims of political, economic and monetary union
The EU also needs to be able to integrate new members.
Benefits of EU enlargement
- increased prosperity for all member states: 3 times more trade exchanges between old and new member states, 5 times more among new member states
- more weight for the EU in global affairs

Potential candidate countries
Bosnia and Herzegovina - application submitted in February 2016
* This designation is without prejudice to positions on status, and is in line with UNSCR 1244/1999 and the ICJ opinion on the Kosovo declaration of independence.
The renewed consensus on the enlargement agreed at the European Council meeting in December 2006, continues to guide EU enlargement policy. EU leaders agreed to pursue a strategy based on:
- the consolidation of EU commitments to ongoing accession negotiations
- a fair and rigorous conditionality at all stages of negotiations with candidate countries
- greater transparency and better communication to ensure broad and sustained public support
- the EU's capacity to integrate new members
The Western Balkans
The European Council meeting in Thessaloniki on 19-20 June 2003 affirmed its determination to fully support the European perspective of the Western Balkans countries.
At a EUCO meeting in December 2006, EU leaders confirmed that the future of the Western Balkans lies in the European Union.
The Western Balkans will become an integral part of the EU once they fully comply with:
- the accession criteria
- the conditions established in the Stabilisation and Association Process (SAP)
In the Council
The General Affairs Council (GAC) configuration establishes and supervises the EU enlargement process and accession negotiations. When a country submits an application to join the EU, the Council invites the European Commission to submit its opinion on this application.
The GAC decisions open a technical evaluation procedure that will determine whether:
- the country meets all the necessary criteria for consideration as an official candidate for EU membership
- formal membership negotiations can be opened and successfully closed
- the candidate country can join the EU
All decisions taken at the GAC to evaluate progress made by candidate countries require unanimous agreement between the 28 EU member states
Every December the GAC takes stock of the enlargement process. The discussion and any potential decisions are based on the Commission's annual enlargement strategy and individual progress reports on each enlargement country. These are traditionally published in October.
On 13 December 2016 the General Affairs Council discussed the enlargement and stabilisation and association process, following which the presidency noted that there was no consensus allowing for the adoption of Council conclusions on this issue. The presidency therefore drew up a set of conclusions which received the support of the overwhelming majority of delegations in the course of the discussions.
On 15 December 2015 the Council adopted conclusions on:
- the EU's enlargement policy, covering Turkey, Montenegro and Serbia
- the EU-Western Balkans stabilisation and association process, covering the Former Yugoslav Republic of Macedonia, Albania, Bosnia and Herzegovina and Kosovo
The conclusions reaffirm the Council's commitment to the enlargement process and to the European perspective of the Western Balkans.
