Russia–Ukraine Mediation and the Black Sea Grain Initiative: Türkiye's Diplomatic Record

Why It Matters

Türkiye is the state that hosted the most substantive face-to-face Russia–Ukraine diplomacy since the February 2022 invasion, and it co-created the one wartime arrangement that let Ukrainian grain leave its Black Sea ports under a mutually accepted inspection regime. The Black Sea Grain Initiative delivered roughly 33 million tonnes of cargo before Russia declined to extend it in July 2023. Understanding how it was built, and why it lapsed, is the clearest practical test of what mediation can and cannot do in an active war.

Background

The initiative grew out of a food-security crisis. Before 2022, Ukraine was a leading exporter of wheat, maize and sunflower oil, and most of that trade moved by sea. After the invasion began on 24 February 2022, Ukrainian ports were blockaded or unusable, and global food prices climbed to record highs. The UN Food and Agriculture Organization's food price index peaked in March 2022.

Chronology of Türkiye-hosted diplomacy

How the corridor worked

The 2022 package consisted of two parallel texts. In the first, Türkiye, Ukraine and the UN set up a safe maritime route from three Ukrainian ports: Odesa, Chornomorsk and Pivdennyi. In the second, Russia and the UN Secretariat agreed a memorandum on facilitating Russian food and fertilizer exports. A Joint Coordination Centre (JCC) in Istanbul, staffed by officials from Türkiye, Russia, Ukraine and the UN, managed ship registration and inspections. Vessels were checked in Turkish waters near Istanbul to confirm that outbound ships carried only agricultural cargo and inbound ships carried no weapons.

The UN counted nearly 33 million tonnes of grain and other food moved through the corridor, aboard roughly 1,000 vessels. The World Food Programme bought more than 700,000 tonnes for humanitarian operations under the scheme. Food prices fell from their March 2022 peak, although the UN and analysts attribute that to several factors, not the corridor alone.

Why it lapsed

Russia's stated reason was that the second text, on its own exports, had not been fulfilled. Moscow pointed to the reconnection of the Russian Agricultural Bank (Rosselkhozbank) to the SWIFT payment system, insurance and port access, spare parts, and the restart of an ammonia pipeline to Odesa. It also argued that too little grain reached the poorest countries. Russia announced on 17 July 2023 that the initiative would not be extended, and later warned that ships heading to Ukrainian ports could be treated as potential carriers of military cargo.

Key Players & Positions

Russia

According to statements by President Putin, the Foreign Ministry and spokesperson Dmitry Peskov, Russia would return to the deal if its part of the package were implemented. Moscow framed the lapse as a failure of the West and the UN to deliver the memorandum, not as a Russian rejection of the corridor itself.

Ukraine

Kyiv, through President Zelensky and its Foreign and Infrastructure ministries, called Russia's exit a deliberate weaponization of food supplies. After July 2023, Ukraine opened its own temporary shipping route along the coasts of NATO members Romania and Bulgaria, and continued exports without Russian consent. Ukraine also supports Turkish hosting of talks, though its own peace formula insists on the restoration of its internationally recognized borders.

United Nations

Secretary-General Guterres called the initiative a humanitarian lifeline and said the UN had worked in good faith to facilitate Russian exports, noting that food and fertilizers are not subject to Western sanctions. UN officials involved in the process included Rebecca Grynspan of UNCTAD, who led the effort on the Russian side of the package.

European Union

The EU, including High Representative Josep Borrell, argued that its sanctions exempt Russian food and fertilizer, and held Russia responsible for ending the deal. Separately, the EU's 'Solidarity Lanes' (launched in May 2022) moved Ukrainian grain overland to EU ports and remained a key alternative route.

Other actors

Importing states in Africa, the Middle East and Asia were the main beneficiaries of lower prices, and many expressed regret at the lapse. Critics in some Western capitals say Türkiye's decision not to join Western sanctions on Russia has given Moscow economic breathing space, a point Ankara rejects (see below).

Source Comparison

Different sources emphasize different causes of both the deal's success and its collapse. The table summarizes the framing; for how this site separates documented fact from stated position, see Editorial Principles.

Two caveats apply. First, no source presents a fully neutral account: figures on cargo destinations vary by methodology. Second, many claims about Türkiye's economic benefits from the war are contested in each direction; readers can consult Fact Check: Common Claims About Türkiye in International Media for the site's approach to such claims.
