Tensions between Turkey, Greece, and Cyprus have escalated significantly as Turkey moves to codify its “Blue Homeland” (Mavi Vatan) doctrine into national law. This legislation, expected to pass in June 2026, seeks to formalize Turkey's maritime claims in the Aegean and Eastern Mediterranean, including the assertion of an Exclusive Economic Zone (EEZ) extending up to 200 nautical miles. Greece and Cyprus have denounced these moves as illegal provocations that violate international maritime law and threaten regional stability. The European Commission has formally stalled Turkey's customs union modernization, linking progress to the “good neighbour” principle and Turkey's conduct regarding Cyprus. On the energy front, the Republic of Cyprus is transitioning from exploration to commercial production. Following a final investment decision by a consortium led by TotalEnergies and Eni, the $2 billion Cronos undersea gas field project is moving forward. McDermott has secured a subsea contract valued between $500 million and $750 million from Eni to provide project management, engineering, procurement, and installation support for the field. The technical design involves four subsea wells connecting to existing infrastructure in Egypt. In September 2026, ~~Egyptian President Abdel Fattah el-Sisi, Greek Prime Minister Kyriakos Mitsotakis,~~ Egyptian, Greek, and Cypriot ~~President Nikos Christodoulides~~ leaders met in El Alamein to reaffirm their commitment to transporting Cypriot gas to ~~Europe.

In Greece, Prime Minister Kyriakos Mitsotakis announced that exploratory drilling, led by a consortium including ExxonMobil, is expected to begin in spring 2027, marking the country’s first such drilling since 1970.
