United Nations chief Antonio Guterres will return to Switzerland to attend talks to reunite Cyprus on Thursday because it is "opportune," his spokesman said on Wednesday.
Guterres was in the Swiss resort of Crans-Montana on Friday - on the third day of negotiations - to lend his weight to the effort to unite Cyprus under a federal umbrella.
"The Secretary-General feels that his presence in the talks would be opportune tomorrow. There have been also a number of calls from the parties for him to return," UN spokesman Stephane Dujarric told reporters.
Guterres said on Saturday that a "clear understanding" had been reached at the talks between Greek Cypriot and Turkish Cypriot leaders and their backers on what was needed to reach a comprehensive agreement to reunite the island.
Greek Cypriot leader Nicos Anastasiades said on Wednesday he would submit proposals to overcome a deadlock that had become apparent over the past week of talks.
