Prime Minister Alexis Tsipras held a meeting at the Foreign Ministry on Tuesday to clarify responsibilities among ministers and staff since assuming the foreign affairs portfolio following Nikos Kotzias' resignation.

Diplomatic sources said that departments and the UN and NATO sections of the ministry will be jointly assumed by Tsipras and Alternate Foreign Minister Giorgos Katrougalos. Tsipras will be solely responsible for the departments related to the Balkans, Turkey and Cyprus.

The meeting also focused on the extension of the territorial waters of Greece, starting at the Ionian Sea, and how the briefings and talks with parties would be carried out. Tsipras decided that the ministry's experts council should convene to weigh in on the issue. He also gave directives on responses to the Turkish government on recent developments.

Other topics of discussion included Greek-Turkish relations in general, Tsipras' preparations for a visit to Turkey following an invitation by its president, Recep Tayyip Erdogan, relations with Albania and the US, and his upcoming visit to Russia.

The meeting participants included, diplomatic sources said, Katrougalos, FM deputy ministers and the secretary general, Tsipras' diplomatic office director and the head of his office of international and European relations.
