Tensions between Greece and Turkey persist regarding maritime sovereignty and energy infrastructure in the Aegean and Eastern Mediterranean. Greek Foreign Minister Giorgos Gerapetritis has affirmed Greece’s military readiness, stating the nation will respond dynamically with frigates and F-16 fighter jets if provoked. He specifically highlighted the need to protect projects like the Great Sea Interconnector (GSI) against Turkish interventions.

In recent statements, Gerapetritis noted that the preconditions for substantive discussions with Turkey regarding a compromise that could lead to international adjudication at the International Court of Justice in The Hague have not yet been met. He emphasized that while Greece has invested in structured dialogue with Ankara over the last three years, the positions of both nations remain essentially different. He accused Turkey of attempting to include “arbitrary and unsubstantiated claims” regarding Greek sovereignty in such processes, maintaining that matters of sovereignty are non-negotiable.

Gerapetritis clarified that Athens recognizes only the delimitation of the continental shelf and the Exclusive Economic Zone (EEZ) as the sole disputes capable of being referred to international jurisdiction. He also addressed Greece’s right to extend its territorial waters to 12 nautical miles and reaffirmed the European dimension of the GSI electrical interconnection project with Cyprus, noting the involvement of the French company Meridiam. He reiterated Greece's commitment to international law and its strategic defense agreements, including its partnership with France.
