Greek, Greek Cypriot and Egyptian defence ministers agree in Cairo on joint protection of East Med energy infrastructure and rapid joint response
At the 6th trilateral defence ministers' meeting in Cairo on 22 September, the 3 countries agreed to strengthen protection of gas fields, supply lines and offshore energy infrastructure and to build a capacity for rapid, unified response to threats. The decision coincided with Erdoğan's call at the UN the same day for recognition of the TRNC.
According to Cyprus Mail, Greek Cypriot Defence Minister Vasilis Palmas, Greek Defence Minister Nikos Dendias and Egyptian Defence Minister Lieutenant General Ashraf Salem Zaher signed a joint statement at the 6th trilateral meeting held in Cairo on 22 September. The statement covered strengthening the joint protection of gas fields, supply lines and offshore energy infrastructure in the Eastern Mediterranean against various threats and deepening military cooperation in light of recent developments in the region. ProtoThema wrote that the parties agreed to intensify communication, consultation, information sharing and the coordination of joint capabilities in order to enhance their capacity to respond rapidly and in a unified manner to future threats. The next meeting will be held in Greece in 2027.
The statement does not name Türkiye, but it contains an explicit reference to the UN Convention on the Law of the Sea (UNCLOS). Türkiye is not a party to the convention, and the dispute over maritime jurisdiction in the Eastern Mediterranean is the main issue between Ankara and Athens–Nicosia. On the same day, 22 September, President Erdoğan called on the international community at the UN General Assembly to recognise the TRNC and repeated his proposal for a regional conference on the Aegean and the Eastern Mediterranean. The Turkish Navy's Denizkurdu-I/2026 exercise, involving 100 ships, 50 aircraft and 14,000 personnel, was also under way that week. The statement also welcomed the recently completed joint Medusa exercise; the date of the exercise and the number of participating units were not given in these sources.
Talay assessment
Bottom line
The Cairo statement is not a new alliance but the militarisation of an existing trilateral mechanism now in its 6th round: the language of joint protection of energy infrastructure and rapid joint response moves the maritime jurisdiction dispute onto the security agenda. Erdoğan's call the same day for recognition of the TRNC and the Denizkurdu exercise show both sides hardening their positions. The most likely path is tension through exercises and statements without direct contact.
Likely effects
- Türkiye's Eastern Mediterranean fileNegative1–6 months
A defence framework grounded in UNCLOS ties a legal basis to which Türkiye is not a party to security cooperation and makes it harder for Ankara's regional conference proposal to gain traction.
- Energy projectsUncertain1–6 months
Placing gas fields and supply lines under military protection may increase the pricing of political risk in exploration and pipeline projects in the region.
- Türkiye–Greece dialogueNegativeWeeks
Mutual military signalling during a fragile period of dialogue could delay the timetable for exploratory talks.
Possibilities, ranked
- 1Tension at the level of statements60%
The parties signal their positions through exercises and statements, with no direct contact at sea.
Watch: The Turkish Foreign Ministry's response to the Cairo statement and NAVTEX notices
- 2Concrete joint patrols25%
The three countries announce joint naval patrols around the gas fields or a permanent coordination centre.
Watch: An announcement of joint patrols or a new exercise by the three ministries
- 3Stronger dialogue channel15%
Türkiye–Greece contacts gain pace and the military rhetoric softens.
Watch: A date being announced for the Türkiye–Greece High-Level Cooperation Council
