On November 11, 2026, Greece and the Republic of Cyprus issued separate counter-notices to Türkiye's claim of consent for the French-flagged Great Sea Interconnector survey vessel. At COP31 in Antalya, the European Bank for Reconstruction and Development announced a five-year $6 billion investment plan.
GSI | Two Counter-NAVTEX Notices and an Unreleased French Letter
Greece and the Republic of Cyprus challenged Türkiye's latest navigational warning for the Abeille Marengo with separate notices on November 11. The French-flagged vessel had left Heraklion the previous evening to prepare seabed surveys for the Great Sea Interconnector (GSI).
Türkiye's TURNHOS 1127/26 notice of November 10 says the survey routes were coordinated with Turkish authorities and consent obtained. Ankara places them within its NAVTEX service area and claimed continental shelf. Four days earlier, its notices 1105/26 and 1106/26 had said the consent procedure was incomplete. The latest warning does not identify the approving authority.
The Greek counter-notice, 1441/26, rejects Türkiye's warning and says the vessel is proceeding under Greek navigational instructions. Athens cites permits 31373, 9020 and 65808, dated June 7, 2024, February 11, 2026 and November 6, 2026. Greek Foreign Ministry sources told Bosphorus News that only Greece and the Republic of Cyprus had received work-permit applications. Prime Minister Kyriakos Mitsotakis acknowledged France's diplomatic notification to Ankara, but said Paris had requested no Turkish permission and created no legal precedent. France has not released the note.
The Republic of Cyprus's Larnaca Joint Rescue Coordination Center issued notice 352/26, rejecting the Turkish warning as uncoordinated with its authorities. It cited licence 05/2026 for work in the Republic's claimed exclusive economic zone and continental shelf, together with its earlier NAVTEX 345/26.
The disagreement concerns preparatory seabed research and the French notification at the centre of the competing permit accounts. Greece invokes the right to lay submarine cables under the United Nations Convention on the Law of the Sea. Türkiye, which is not a party to the convention, says research on its claimed continental shelf requires consent.
COP31 | REACT Financing and Diplomacy in Antalya
At the COP31 leaders' summit in Antalya, President Recep Tayyip Erdoğan set out ten areas for climate implementation, including clean energy, zero waste, food security, industry, resilient cities and ocean protection. He promoted the Climate Implementation Bridge (BRIDGE), announced in September, to connect local projects with investors.
United Nations Secretary-General António Guterres called for an international climate justice compact. He urged developed countries to deliver at least $300 billion a year in climate finance by 2035, cited a broader $1.3 trillion target for flows to developing countries and pressed for steeper emissions cuts, more adaptation finance and measures addressing extraordinary profits from fossil fuels.
The summit also brought a financing announcement for Türkiye. The European Bank for Reconstruction and Development (EBRD) joined the Renewable Energy Acceleration and Clean Transition Platform (REACT) and announced plans to invest $6 billion over five years in Türkiye-related projects. The platform aims to mobilize $300 billion by 2040 for renewable power, grids, storage, manufacturing and electrification, with support from the European Union, World Bank Group institutions and other development and climate-finance bodies.
Türkiye is targeting 175 gigawatts of combined solar and wind capacity by 2040. REACT will work on project selection, financing and transmission-grid investment alongside the electricity corridor and Saudi renewable-energy programme described in the November 10 brief.
Erdoğan used the summit for talks on regional transport links. Armenian Prime Minister Nikol Pashinyan discussed normalization, trade and steps toward the Trump Route for International Peace and Prosperity (TRIPP). Chinese Vice President Han Zheng discussed the Middle Corridor, China's Belt and Road Initiative and Iraq's Development Road.
Erdoğan's remarks on Israel's conduct in Gaza drew a sharply worded response from the Israeli Foreign Ministry. Türkiye's Foreign Ministry rejected the allegations in statement No. 218 on November 11 and reaffirmed its support for Palestinians.
Cyprus | EU Trade Proposal and Preparations for Two Crossings
Cyprus News Agency reported on November 11 that European Commission Executive Vice-President Raffaele Fitto planned to discuss a possible offer to open EU–Türkiye Customs Union upgrade talks if Cyprus settlement negotiations resume.
The Commission confirmed that Republic of Cyprus President Nikos Christodoulides and Commission President Ursula von der Leyen discussed the Cyprus process, Fitto's planned Türkiye visit and the Republic's Schengen bid in Antalya. Fitto is scheduled to meet Turkish Foreign Minister Hakan Fidan in Ankara on November 20. The proposed Customs Union condition comes from the agency's reporting, rather than a public Commission decision.
Following the November 9 agreement on two crossings, Greek Cypriot technical-committee members were preparing to meet, with joint discussions and site inspections still to follow. Preparations focus particularly on Kambo/Kampos–Gemikonağı/Karavostasi, where road conditions, property issues and access through the UN buffer zone need attention. Akıncılar/Louroujina–Limya/Lympia involves a shorter route. The leaders agreed that both crossings would open simultaneously; the date is still to be fixed.
Turkish Cypriot President Tufan Erhürman attended the COP31 opening at Erdoğan's invitation and briefly met Guterres, Fidan and other officials. Prime Minister Ünal Üstel met Turkish Vice President Cevdet Yılmaz. The two-crossing agreement has also exposed an executive-authority dispute within the Turkish Cypriot leadership: Üstel supports crossings that serve both communities, while Foreign Minister Tahsin Ertuğruloğlu objects to the political terms and says the government was bypassed.
Üstel also promoted two Türkiye–TRNC energy links in Antalya: a submarine electricity cable intended to support a cleaner power mix and a natural-gas pipeline intended to reduce fuel-oil use. Both projects are being discussed as part of the Turkish Cypriot side's energy transition plans.
Eastern Mediterranean | NEMESIS, Offshore Security and the Libya Dispute
NEMESIS 2026 concluded on November 11 in maritime areas claimed by the Republic of Cyprus. Its Defense Ministry listed personnel from the Republic of Cyprus, Greece, France, the United Kingdom, the United States, Israel, Italy and Egypt, as well as four private companies and European agencies. The exercise rehearsed responses to threats against offshore gas facilities, maritime security incidents and emergencies.
Türkiye's Mavi Balina-2026 anti-submarine exercise involved Turkish, Greek and Spanish vessels from Standing NATO Maritime Group 2, together with US and Pakistani participants. Greek forces were active in both exercises, whose tasks and command structures differ.
The parliamentary speakers of Greece, the Republic of Cyprus and Egypt met in Nicosia on November 11 and adopted a joint declaration addressing maritime law and energy cooperation. Greek Parliament Speaker Nikitas Kaklamanis objected to the 2019 Türkiye–Libya maritime boundary memorandum, arguing that it disregards Greek islands' maritime entitlements.
Greece announced a €35 million investment by the Hellenic Innovation and Infrastructure Fund in Finnish radar-satellite company ICEYE, with satellite production and integration planned in Greece. Signed in September and completed in October, the transaction was made public on November 11. Radar imagery could also serve maritime surveillance. In another defense-technology development, Anduril presented its Lattice command-and-control software to Greek military staffs on November 10.
Black Sea & Ukraine | Abu Dhabi Prisoner Talks and Maritime Preparations
Russian and Ukrainian negotiators left Abu Dhabi on November 11 with an agreement in principle on a major prisoner exchange, according to the negotiating parties. Details of the exchange are under discussion. No ceasefire was agreed for the wider war or for commercial shipping in the Black Sea.
The Group of Seven foreign ministers condemned attacks on civilian shipping in the Black Sea in their November 11 declaration. Türkiye leads the maritime planning element of the UK- and France-led Coalition of the Willing, whose Istanbul-based staff are taking part in KOALICJA 26.2 on November 9–22. The prospective postwar mission is separate from Türkiye's existing mine-countermeasures cooperation with Romania and Bulgaria.
Türkiye | Kavcıoğlu Seeks Departure as Fund Inquiry Brings New Arrests
Şahap Kavcıoğlu, chairman of Türkiye's Banking Regulation and Supervision Agency (BDDK), said on November 11 that he had asked President Erdoğan to relieve him of his duties, citing allegations concerning himself and the agency. The presidency had not announced a decision on the request or a successor by the edition cutoff.
An Istanbul judgeship ordered the pretrial detention of former Takasbank general manager Yunus Arıncı, OMG Capital Advisors chairman Ömer Murat Gülkan and Adil Katılım Bankası shareholder Ali Paslı in the capital-markets investigation. Enver Çevik, Nureddin Çevik, Kemal Akkaya and Ayhan Yazkan were placed under judicial control.
The inquiry covers investment funds, company holdings and alleged irregular market transactions. It has included arrests involving a banking regulator and a bank executive and a wider asset-freeze investigation. Bloomberg, in reporting cited by Karar, quoted economists and market specialists concerned about the effect on investor confidence and the adequacy of regulatory oversight.
Syria & Lebanon | EU Draft and Attack on UNIFIL Patrol
A draft EU diplomatic paper reviewed by Reuters on November 11 proposes broader engagement with Damascus ahead of the November 16 foreign ministers' meeting. It covers security reform, police training with Jordan, investment, possible revival of a 2008 association agreement and Russia's military presence at Tartus and Hmeymim.
The United Nations Interim Force in Lebanon (UNIFIL) reported about a dozen shots fired at a patrol near Wadi Jilu on November 10. Peacekeepers returned fire; nobody was injured. UNIFIL requested a Lebanese investigation. Its mandate expires on December 31, with a phased withdrawal to follow. Türkiye contributes personnel to the force.
Iraq | PUK Cabinet Boycott and NATO Advisory Mission
The Kurdistan Regional Government called on Patriotic Union of Kurdistan (PUK) ministers to return after they boycotted the November 11 cabinet meeting. Ministers also discussed Baghdad's draft 2027 budget and damage from the earlier attack on the Khor Mor gas field, which cut electricity supplies.
The commander of NATO Mission Iraq briefed the alliance's Military Committee and North Atlantic Council on November 9–10. The non-combat advisory mission now operates from Allied Joint Force Command Naples, following the March relocation of personnel from Iraq. Ankara and Baghdad are pursuing the Başika handover and Sincar arrangements through bilateral channels.
Hormuz & Iran | Another Tanker Incident and US Interdiction Plans
United Kingdom Maritime Trade Operations issued warning 202-26 on November 11 after a tanker incident in the Strait of Hormuz. The initial report gave no details on the crew, damage or pollution. On November 10, another tanker reported being struck by an unidentified projectile 19 nautical miles northeast of Lima, Oman; its crew were safe and no pollution was reported.
The US military announced Task Force Iron Gate on November 7 to coordinate efforts against illicit Iran-related transfers along land and Caspian routes. Its remit covers land and Caspian routes alongside Washington's maritime pressure around Hormuz.
NATO & Defense | Bulgaria Force Test and Precision-Strike Work
Turkish land forces are participating in Tracia-2026 at Bulgaria's Novo Selo training area from November 9 to 26. The exercise tests assembly and readiness procedures for expanding NATO's forward forces in Bulgaria from battlegroup to brigade strength, Türkiye's Defense Ministry said.
NATO met allies and defense-industry representatives in Brussels on November 10 to discuss long-range precision strike systems, including cruise missiles, drones and maritime strike weapons. Türkiye joined a six-country land-based precision-strike initiative at NATO's July defense-industry forum in Ankara.
Bosphorus Read
The GSI dispute has a documentary question and a financing problem. France's diplomatic note would clarify the nature of its contact with Ankara, while the Abeille Marengo's logs would establish where survey equipment was used. The project's next construction stage also depends on the Republic of Cyprus's pending €25 million contribution and agreement over eligible costs. Progress at sea will not itself release the money.
REACT puts Türkiye's grid investment needs alongside its renewable-generation targets. The five-year EBRD plan could help projects reach financing, but the much larger $300 billion goal requires other investors and transmission capacity. The first signed grid contracts and project loans will offer a clearer measure of implementation than the platform's launch.
The agreement on two Cyprus crossings now enters ministries whose political leadership is divided over its terms. Road access and staffing will show whether that dispute affects implementation. The separate, reported EU Customs Union offer could put a concrete economic incentive into Ankara's Cyprus discussions. Fitto's November 20 meeting with Fidan is the next opportunity to establish whether the Commission intends to make such an offer formally.
Greek forces joined a Republic of Cyprus-led offshore-security exercise and Türkiye-hosted anti-submarine training in the same week. The exercises have different command structures and purposes. Participation in either reveals little about whether Athens and Ankara can reach an understanding on survey permissions: that argument remains with the diplomatic and maritime authorities.
Postwar maritime planning around Ukraine still needs answers on operational authority, port access and the point at which a multinational force could begin work. Türkiye's existing mine-countermeasures cooperation with Romania and Bulgaria provides experience, but it operates under a different mandate. Abu Dhabi has produced a prisoner-exchange understanding, not the maritime arrangements on which a future deployment would depend.
The fund investigation now warrants a dated account of regulatory action. When did supervisors identify unusual activity, which warnings reached them, and when were restrictions imposed? Those records would allow the public to assess the oversight questions alongside the new detention orders, rather than treating the judicial decisions as a complete account of the crisis.
