Disputed territory

Further information: Cyprus problem

The northern part of Cyprus is legally part of the EU, but the terms of the acquis communautaire, the EU's body of laws, have been suspended due to it being under the control of the Turkish Republic of Northern Cyprus, a self-proclaimed de facto state which is recognized only by Turkey. The two entities are separated by the United Nations Buffer Zone in Cyprus, which serves as a de facto boundary between them.

Border status and cooperation

In 2004 the European Union developed the European Neighbourhood Policy (ENP) for the promotion of cooperation between the EU and its neighbours to the east and south of the European territory of the EU (i.e., excluding its outermost regions outside of Europe),^[2] which, in part, includes the Cross-Border Cooperation programme aimed at the promotion of economic development in border areas and ensuring border security.^[3]

External border control

The Border and Coast Guard Agency, more commonly known as Frontex, was established in 2004. Its main task is external border control of the Schengen Area. Most of its activities are coordinated with the coast and border guards of member states.

Notes

1. The Overseas Countries and Territories (OCTs) are not part of the EU but they are associated with it. They depend to varying degrees on the Member States which have sovereignty over them.
2. Unlike the French side of the island, Sint Maarten is not part of the EU. It is among the Overseas Countries and Territories of the EU.
3. The Channel Tunnel links the two countries underground and is defined as a 'land frontier', but it is not widely recognised as a land border.
