Brussels, Belgium – Representatives from Greece and Turkey are due to meet at NATO headquarters in Brussels on Tuesday for technical military talks aimed at de-escalating tension in the Eastern Mediterranean, diplomatic sources in Greece said on Monday.

NATO Secretary-General Jens Stoltenberg has been trying to bring the two sides to the table to discuss a “deconflicting mechanism” that would help avert a crisis between the neighbors and NATO allies over maritime and energy rights in the Eastern Mediterranean.

Tuesday’s meeting will come two days after Turkey’s Oruc Reis seismic survey ship returned to the port of Antalya and after Turkey allowed a navtext reserving disputed parts of the region for surveys to expire on Saturday, without renewing it.

The two moves were the result of efforts by NATO to break the deadlock between Greece and Turkey, though the Turkish ministries of Energy and Defense went on to claim that the Oruc Reis’ return to Antalya was part of its routine maintenance and supply schedule.
