Erdogan gives ultimatum over rival claims in Mediterranean

ANKARA, Turkey — Turkish President Recep Tayyip Erdogan on Saturday warned Greece to enter talks over disputed eastern Mediterranean territorial claims or face the consequences.

“They’re either going to understand the language of politics and diplomacy, or in the field with painful experiences,” he said at a hospital’s opening ceremony in Istanbul.

Ankara is currently facing off against Greece and Cyprus over oil and gas exploration rights in the eastern Mediterranean. All sides have deployed naval and air forces to assert their competing claims in the region.

“They are going to understand that Turkey has the political, economic and military power to tear up the immoral maps and documents imposed,” Erdogan added, referring to areas marked by Greece and Cyprus as their economic maritime zones.

Meanwhile, Turkish media reported that tanks were being moved towards the Greek border. The newspaper Cumhuriyet said

40 tanks were being transported from the Syrian border to Edirne, in northwestern Turkey, and carried photographs of armored vehicles loaded on trucks.

The president’s comments come after NATO said military officers from Greece and Turkey had begun technical discussions to reduce the risk of armed conflict or accidents.

The two NATO allies have been locked for weeks in a tense standoff in the eastern Mediterranean, where Turkey is prospecting the seabed for energy reserves in an area Greece claims as its own continental shelf.

Ankara says it has every right to prospect there and accuses Athens of trying to grab an unfair share of maritime resources.

Simulated dogfights between Greek and Turkish fighter pilots have multiplied over the Aegean Sea and the eastern Mediterranean.

Erdogan said Turkey had repeatedly expressed its willingness to come to a just agreement.

Turkey faces a wide range of opponents in the eastern Mediterranean. France, Italy and the United Arab Emirates have sent forces to join war games with either Greece or Cyprus in recent weeks. Egypt has signed an energy exploration deal with Athens for the Mediterranean.

The European Union, which counts Greece and Cyprus as members, has also threatened possible sanctions against Ankara over its “illegal” actions.

This week, the U.S. announced it was easing a 33-year-old arms embargo against ethnically divided Cyprus.

The island split in 1974 when Turkey invaded following a coup by supporters of union with Greece. Turkey is the only nation to recognize a Turkish Cypriot declaration of independence, and it maintains more than 35,000 troops in northern Cyprus.
