Delegations from Greece and Turkey were meeting in Athens on Monday as part of long-standing efforts to improve often tense relations between the two neighbors, days after Turkey voiced objections over Greece’s plans to create marine nature reserves in the Ionian and Aegean seas. Monday’s meeting in the Defense Ministry in Athens was to discuss confidence-building measures, following a similar meeting in Ankara last November. The meeting comes ahead of planned talks in Ankara on May 13 between Turkish President Recep Tayyip Erdogan and Greek Prime Minister Kyriakos Mitsotakis.
