Turkey is said to be discussing a mechanism with Russia and Ukraine a mechanism to prevent attacks on ships in the Black Sea, RIA reports, citing Turkish cabinet source

Turkey has occupied this brokerage role before: Ankara's geographic control of the straits and its maintained relations with both Moscow and Kyiv have made it the recurring intermediary for Black Sea maritime arrangements, most notably the wartime grain corridor frameworks, and Turkish mediation efforts have historically been credible in structure even where durability proved limited. The operative channel for such arrangements has been freight, war-risk insurance premia and the willingness of commercial carriers to load, which have tended to reprice on the credibility of enforcement rather than on the announcement of talks; prior corridor episodes showed insurance costs falling only once sailings actually resumed and held. The case distinction here is between a narrow naval de-confliction mechanism and a broader commercial shipping guarantee: the former limits military incidents, the latter is what moves grain, fertilizer and energy flows out of the region. Worth noting is the sourcing, a Russian state agency citing a Turkish cabinet official, which in past episodes has meant the initiative is at an early, deniable stage and subject to contradictory readouts from the other parties. The tells are confirmation from Kyiv and Ankara in their own words, any reference to inspection or monitoring architecture, and whether existing security guarantees from other parties are referenced or displaced. As an opening report rather than an agreed framework, this sits at the speculative end of the sequence that has preceded prior Black Sea arrangements.
