'Be creative': U.N. chief says as Cyprus talks open

"The parties are welcome to be creative and the Secretary-General will be encouraging them to use diplomatic language in a sincere and frank manner," U.N. spokesman Stephane Dujarric said at a U.N. briefing.

The UN has invited the Mediterranean island's two communities, the Greek Cypriot leader, Nicos Anastasiades and his Turkish counterpart, Ersin Tatar, as well as foreign ministers of Turkey, Greece, and Britain, to attend the Geneva-based talks this week in an effort to resume peace negotiations that collapsed in mid-2017.

Previous talks on reunification under a federal umbrella, as called for in U.N. resolutions, have failed. Northern Cyprus has since called for a two-state solution, but Greek Cypriots - who form the island's internationally recognized government - reject this as it implies Turkish Cypriot sovereign authority.

The talks will begin late afternoon on Tuesday (April 27) with bilateral meetings between the two island communities and Guterres followed by a meeting with all parties on Wednesday.
