The Republic of Cyprus (ROC) collaborated closely with the United States, the European Union, and others –bilaterally and multilaterally– in international counterterrorism efforts in 2022. Since 1974, the island of Cyprus has been de facto divided into the ROC government-controlled area in the southern two thirds of the island and the northern third administered by Turkish Cypriots. A UN peacekeeping force patrols a Buffer Zone, also called the Green Line, that separates the two sides. The Buffer Zone is largely open to civilian traffic and remains a significant route for the illicit transit of people, narcotics, and other contraband. The division of the island has impeded counterterrorism cooperation between the two communities and between the ROC and Türkiye, which do not maintain diplomatic relations.
