The Western Balkan countries are all in a process of accession to the European Union. Croatia, Macedonia and Montenegro have the status of candidate countries. Albania, Serbia, Bosnia and Herzegovina and Kosovo under UNSCR 1244/99 are potential candidate countries, with the prospect of joining the EU when they meet the established conditions. During pre-accession, the candidate countries go through a process in which they review all their national legislation and policies with a view to harmonizing it with the EU acquis communautaire. They also have to adapt their institutions and economic policies, strengthen the rule of law and develop market-oriented economies.
