Turkey is establishing a Maritime Component Command in Istanbul's Beykoz district as part of the 'Coalition of the Willing for Ukraine,' a 33-country multinational framework preparing postwar security arrangements. Defense Minister Yaşar Güler's letter reveals Turkey will lead maritime security operations in the Black Sea while respecting the Montreux Convention. This marks a significant shift from Ankara's longstanding policy of limiting foreign military involvement in the Black Sea. The initiative includes a core Turkish staff established in August 2025, with 14 countries contributing to the command structure. Critics question whether the project, despite being under Turkish command, effectively integrates with NATO planning and could strain relations with Russia.

Russian Security Council Secretary Sergey Shoygu told Turkish Foreign Minister Hakan Fidan during a meeting in Moscow that Western interference prevented the implementation of the 2022 Istanbul agreement on Ukraine, despite joint efforts by Russia and Turkey. Shoygu also accused UN Secretary-General Antonio Guterres of failing to fulfill commitments related to the Black Sea grain initiative. The meeting highlighted ongoing Russia-Turkey cooperation on Syria and Ukraine-related issues, including the return of Turkish vessels from Ukrainian ports.

Russia's newly appointed ambassador to Turkey, Sergey Vershinin, said in an interview that Moscow respects Turkey's NATO membership but expects the alliance to adapt to new global realities where military solutions are obsolete. He addressed the Ukraine war, Black Sea security under the Montreux Convention, and the potential for continued Russia-Turkey cooperation in energy and trade. The statements come ahead of the July 7-8 NATO summit in Ankara, highlighting the delicate balance Turkey maintains between its NATO obligations and its relationship with Russia.

Turkish Foreign Minister Hakan Fidan held separate phone calls with Egyptian Foreign Minister Badr Abdelatty and Pakistani Foreign Minister Mohammad Ishaq Dar on June 17, 2026, to discuss the peace process between the US and Iran. The ministers exchanged views on upcoming follow-up negotiations aimed at establishing lasting peace between the two countries. This trilateral coordination marks a new diplomatic effort involving Turkey, Egypt, and Pakistan to support the US-Iran peace process.
