Turkey and Greece will sit down to try to tackle differences over maritime boundaries and offshore energy resources for the first time since 2016.

Diplomats from the two countries will meet in Istanbul on Jan. 25 to begin “exploratory talks,” the Turkish and Greek foreign ministries said late Monday. Greek officials have ruled out expanding the scope of the negotiations to other long-running disputes with Turkey.

“I believe exploratory talks with Greece will be harbinger of a new era,” in relations, Turkish President Recep Tayyip Erdogan told ambassadors from EU member countries in Ankara on Tuesday

The announcement comes just weeks after the European Union (EU) pledged to expand the number of Turkish officials sanctioned over the country’s energy exploration in the disputed waters of the eastern Mediterranean Sea. Cyprus, Greece and France this week proposed a list of potential new targets.

Ankara and Athens are locked in a showdown over conflicting interpretations of maritime borders. Competing claims to sovereignty over waters rich in hydrocarbon reserves led to a naval standoff between Greece and Turkey in 2020.

Another thorn in the relationship is Turkey’s continued control of northern Cyprus, which it seized following a coup attempt in which a military junta in Athens sought to unite the island with Greece.

Cyprus and Greece say Turkey’s maritime claims infringe on their sovereignty and have repeatedly demanded that the EU impose sweeping economic sanctions. Such demands have so far failed to win the required unanimous backing of EU member states, many of which fear an escalation that would break the bloc’s ties with Ankara.

Erdogan has in recent months toned down his mostly confrontational rhetoric toward the 27-nation bloc, saying that Turkey wants a new chapter in relations with the EU. His government last month ordered Oruc Reis, a seismic ship whose offshore surveys angered officials in

On Tuesday, Erdogan urged the EU to honor its promises to Turkey, including updating their customs union and waiving visa requirements for Turkish citizens. He also called on the bloc to update a 2016 deal by which Turkey stemmed the flow of migrants toward Europe in exchange for financial assistance.

Foreign Minister Mevlut Cavusoglu, addressing EU ambassadors earlier on Tuesday, said he and Greek Foreign Minister Nikolaos Dendias have agreed to meet following the exploratory talks in Istanbul.

The blacklist so far includes only two people and has no material consequences for Turkey’s economy. EU officials will start debating the proposed additional listings next week, though it’s unclear whether the latest push will fare any better than previous attempts.
