The Union should also take a clearer stance on the occupation by Turkey of part of Cyprus, he added.
Kotzias, who headed the Greek delegation at the UN-brokered Conference on Cyprus in Crans-Montana, Switzerland, earlier this month, said he would not describe the high-level efforts as “failed”.
“I would say it did not have the results we all expected…From our point of view, some important steps were taken,” he said.
“Most importantly, the issue of security and guarantees has finally been put on the agenda of the negotiations,” he added.
Kotzias also said his view of more than two years ago is that discussion of security and guarantees is the key to unlocking the Cyprus problem and thus should precede negotiation in other chapters.
