UNITED NATIONS — Turkish Cypriot leader Mustafa Akinci says he expects a meeting Sunday with his Greek Cypriot counterpart and U.N. Secretary-General Ban Ki-moon to provide a road map for reunification of the ethnically split Mediterranean island.

Cyprus was divided into a breakaway Turkish-speaking north and an internationally recognized Greek-speaking south in 1974 when Turkey invaded in the wake of a coup aimed at unifying with Greece.

Akinci and his Greek Cypriot counterpart Nicos Anastasiades have said they have made progress on many issues, including on how to share power in a possible federation. But more work needs to be done. Akinci met with Ban on Saturday and Anastasiades met with the U.N. chief on Sept. 18.

“Hopefully tomorrow’s meeting … will indicate the way which will carry us to the long-awaited final conclusion,” Akinci told reporters after meeting with Ban at the U.N. on Saturday.

Ban will not act as an arbitrator but will address concerns if discussions appear to favor one side over the other. He has said that the discussions are “Cypriot-owned and Cypriot-led.”
