Turkey’s defense ministry said Thursday that its recent navigational warnings, or Navtex, in the Aegean Sea were issued without an end date, pushing back on Greek press reports that described the notices as a two-year move to press Turkey’s maritime claims. The statement matters because Navtex is not just a routine maritime safety broadcast. Turkey’s defense ministry said its navigational warnings are “technical objections” to what it calls Greece’s unlawful activity in the Aegean and said they are not limited to a set term. The flare-up comes as Greece and Turkey prepare for new high-level talks expected in mid-February, with Greek and Turkish leaders set to meet in Turkey. On the demilitarization dispute, Turkey points to treaty text including Article 13 of the 1923 Treaty of Lausanne, which set restrictions for Lesbos, Chios, Samos and Ikaria.
