Russian President Vladimir Putin will host Turkish leader Recep Tayyip Erdogan for talks next week, the Kremlin announced Friday, just over six weeks after Moscow broke off a deal brokered by Ankara and the U.N. that allowed Ukrainian grain to reach world markets safely despite the 18-month war.

Kremlin spokesman Dmitry Peskov said Putin and Erdogan would meet Monday in Russia’s Black Sea resort of Sochi.

The announcement ended weeks of speculation about when and where the two leaders might meet next, while international efforts continue to try to patch up the Black Sea Grain Initiative, which sent grain to parts of Africa, the Middle East and Asia where hunger is a growing threat.

Ukraine and Russia are both major global suppliers of wheat, barley, sunflower oil and other commodities that developing nations rely on.

Turkey, together with the United Nations, brokered the deal in July 2022 that allowed Ukraine to resume shipping foodstuffs from three Black Sea ports. Under the initiative, ship and cargo inspections were overseen from Turkey, and vessels sailed to and from Ukraine from there. Almost 33,000 tons of grain left Ukraine while the agreement was in effect.

Ankara’s role was key. Turkey is one of Russia’s main trading partners and a logistical hub for Russia’s foreign trade amid Western sanctions. Erdogan calls Putin “my dear friend.”

A separate memorandum that Moscow and the U.N. agreed to at the same time as the Ukraine initiative pledged to help to overcome wartime obstacles to Russian exports of food and fertilizer. Russian officials repeatedly threatened to pull out of the deals and finally did in July, alleging its conditions hadn’t been met.

Russia has complained that restrictions on shipping and insurance have hampered its agricultural exports, but it has shipped record amounts of wheat since last year.

U.N. Secretary-General Antonio Guterres sent Russia a new proposal in hopes of reviving the deal but it didn’t satisfy Moscow’s demands, Russian Foreign Minister Sergey Russian Foreign Minister Sergey Lavrov said while hosting his Turkish counterpart, Hakan Fidan, for talks in Moscow on Thursday.

Lavrov said he gave the Turkish government a list of actions that the West would have to take in order for Ukraine’s Black Sea exports to resume. The scheduled talks between Putin and Erdogan could help unlock that.

The announcement of Monday’s meeting coincided with the departure of two bulk cargo ships Friday from the Ukrainian port city of Yuzhne.

The Liberia-flagged Anna-Theresa and the Ocean Courtesy, traveling under a Marshall Islands flag, were carrying pig iron and iron ore concentrate, Ukrainian Minister of Infrastructure Oleksandr Kubrakov said.

It was not clear under what legal and security circumstances the ships had sailed.

The Ocean Courtesy was headed to Romania’s Black Sea port of Constanta and is estimated to arrive there Saturday afternoon, according to the global ship tracking website MarineTraffic. The website said the Anna-Theresa would reach Varna in Bulgaria the same day.

Meanwhile, Russian officials said Friday that air defenses intercepted drones heading toward three of the country’s western regions. Regional governors said defense systems stopped three drones in the Kursk, Belgorod and Moscow regions.

Moscow airports briefly halted flights but no major damage or injuries were reported, according to Russian authorities.
