The pace of the European Union’s enlargement has slowed following its historic expansion in 2004-07 to take in 10 countries from Central and Eastern Europe, as well as Cyprus and Malta. From among EU hopefuls which have been given membership prospects – Turkey and Western Balkan countries – only Croatia joined the EU in 2013. Accession negotiations continue with Montenegro, Serbia and Turkey. Iceland has dropped its membership bid. European Commission President Jean-Claude Juncker has said he does not expect any new country to join the EU during his term in office, which ends in 2019, a statement confirmed in the European Commission’s most recent enlargement strategy.
The EU hails enlargement as one of its most successful policies as it enforces reforms in candidate countries and expands the zone of democracy and stability in Europe. But many analysts and politicians say that before expanding further, the EU must overcome its numerous, internal problems as well as give time to potential entrants to prepare themselves for membership, notably in areas such as respect for fundamental rights and anti-corruption policies.
This note offers links to a series of recent studies from major international think tanks and research institutes on the enlargement process and the challenges faced by countries aspiring to EU membership.

I find it utterly amazing that the Commission is not taking into account the very widespread concerns that are related to the expansion of the EU. No one in his right mind believes that the current management of the EU with 28 members is sustainable. To continue with a blind expansion policy will therefore create more antagonistic attitudes to whatever “Brussels” stands for. There must be other ways to get countries to adopt civilized policies and attack corruption. It seems to me that expansion has been driven purely by expansion desires rather than ensuring that candidate countries can become respected members of the EU.at the moment the EU is at risk of breaking apart thus expansion seems like sticking your head into the sand.
