Turkey and Greece at loggerheads over maritime sovereignty
Recently, questions surrounding the ownership of natural resources suspected below the seafloor in the Eastern Mediterranean and, by extension, maritime sovereignty in the region, have seen serious sabre-rattling from both sides. Relations between the NATO partners, situated on the alliance’s fragile south-eastern flank, have seldom been so poor. Yet the altercation has long since ceased to be a bilateral matter involving just Turkey and Greece.
The current tensions were triggered by an announcement from Ankara that it would be sending a vessel to explore waters near the Greek island of Kastellorizo. For Athens, this was and remains a significant provocation; for Ankara, on the other hand, it is business as usual, since the tiny Greek island lies within view of the Anatolian mainland.
The essence of the problem is that Ankara does not want to recognise that the Greek islands form their own continental shelf – as stipulated by international maritime law. While Greece is invoking international law and setting out its legal arguments, Ankara, which has not ratified the UN Convention on the Law of the Sea, is pushing for a political solution.
Much to Turkey's displeasure, the EU has positioned itself decisively behind Greece on this question of territory: “We are determined to protect the EU's external borders and to strongly support Greece's sovereignty,” the EU’s Minister for Foreign Affairs, Josep Borrell, said in late June. The EU’s foreign ministers ultimately backed Athens once again, following their call for de-escalation, urging Turkey to bring an end to its “illegal drilling”.
Confidential discussions in Berlin
The Europeans are not content to leave the matter at rebukes and appeals for change, however: Brussels and Berlin have launched a diplomatic intervention with the aim of persuading President Erdogan to withdraw the exploration vessel and guiding Athens and Ankara to the negotiating table.
Berlin sent a clear signal in its address to Erdogan. Progress in Turkey’s relations with the EU would be contingent upon “Ankara halting its provocations in the East Mediterranean,” in the words of Germany’s Minister for Foreign Affairs, Heiko Maas. To give the estranged neighbours a helping hand, secret discussions were held with emissaries from Athens and Ankara in Berlin in July.
Hopes of a swift resolution did not last long. Meanwhile, Athens and Cairo announced an intergovernmental agreement establishing the maritime borders between Egypt and Greece. Envoys had spent ten years crafting the agreement. The announcement was met by outrage in Turkey.
