Cyprus' government spokesman says that U.N. Security Council member states must take part in an upcoming summit in Geneva aimed at removing a key stumbling block in the way of a deal reunifying the ethnically divided island.

Nicos Christodoulides told The Associated Press on Monday that Security Council members have expressed their readiness to "actively and effectively take part" in next month's summit and that he expects their participation.

He said that the U.N. Security Council, which has been involved in Cyprus talks for decades, should ensure the implementation of a peace accord — something that concerns both Greek and Turkish Cypriots.

The summit will focus on how post-reunification security arrangements will be handled.

Cyprus was split in 1974 when Turkey invaded following a coup aimed at union with Greece.
