Ministry of Foreign Affairs rejects statements by Greek officials with reference to the Treaty of Lausanne
The statement coincided with Fidan's warning over the militarisation of islands with demilitarised status.
In statement No. 179 issued on 14 September, Türkiye's Ministry of Foreign Affairs described as baseless and rejected statements by Greek officials concerning the period of the occupation of Anatolia. The statement referred to Article 59 of the Treaty of Lausanne.
The statement coincided with the day Foreign Minister Hakan Fidan warned Athens over the militarisation of islands with demilitarised status in the Aegean. The hardening of rhetoric between the two countries, together with the energy and maritime jurisdiction files in the Eastern Mediterranean, also forms the backdrop to Türkiye–European Union defence cooperation talks. The reference to Lausanne shows that Ankara considers historical questions closed by the treaty and ties the debates over status in the Aegean to the same legal framework. Whether the hardening of rhetoric has translated into a concrete military step is not, at this stage, supported by verifiable data.
Talay assessment
Bottom line
The statement repeats Ankara's established position of tying historical disputes and the status debates in the Aegean to the Lausanne framework; it signals a hardening of rhetoric rather than a policy shift. As no concrete military step has been verified, the most likely course is for tension to stay at the level of notes and statements, although the same-day warning on the militarisation of the islands raises the risk of the file spilling into Türkiye–EU defence cooperation talks.
Likely effects
- Türkiye–Greece relationsNegativeWeeks
The exchange of statements overshadows the positive agenda in dialogue channels; rhetoric aimed at domestic audiences in both capitals narrows the room for compromise on maritime jurisdiction files in the Aegean and Eastern Mediterranean.
- Türkiye–EU defence cooperationNegative1–6 months
Athens' objections could strengthen the grounds for vetoes and conditions in Türkiye's EU defence cooperation talks, which risks extending the timeline for Ankara's participation in European defence industry projects.
Possibilities, ranked
- 1Tension confined to rhetoric75%
The parties limit themselves to exchanges of statements and notes; existing dialogue mechanisms are not suspended and no new military deployment appears on the ground.
Watch: Planned foreign ministry contacts going ahead and no new military incident reported in the Aegean
- 2Diplomatic tension spreads to the EU file20%
Athens takes the islands' status and the Lausanne dispute to EU forums; conditions harden in Türkiye–EU defence cooperation talks and the process slows.
Watch: Aegean references to Türkiye in EU summit texts and postponement of defence cooperation talks
- 3Concrete escalation on the ground5%
The rhetoric translates into a new armament step on the islands or an incident between air and naval assets in the Aegean; crisis management channels are activated.
Watch: Verified reports of new military assets sent to the demilitarised islands or a mutual interception incident
