From the Summary: "Cyprus has been divided since 1974. Greek Cypriots, nearly 80% of the population, live in the southern two thirds of the island. Turkish Cypriotslive in the 'Turkish Republic of Northern Cyprus' (recognized only by Turkey), with about 30,000 Turkish troops providing security. U.N. peacekeeping forces maintain a buffer zone between the two. Since the late 1970s, the U.N., with U.S. support, has promoted negotiations aimed at creating a federal, bicommunal, bizonal republic on Cyprus. The two sides would pledge not to move toward union with any other country. This reflects concerns that Greek Cypriots would like to unite with Greece and that Turkish Cypriots seek to partition the island, linking the north to Turkey. [...] Members of Congress have urged the Administration to be more active, although they have not proposed an alternative to the U.N.-sponsored talks. Some Members seek increased pressure on Turkey to withdraw its troops from Cyprus."
