Putin and Erdogan’s long-awaited meeting is due to take place in Sochi on Russia’s southwest coast on Monday.
Turkish officials have confirmed that the pair will discuss renewing the Black Sea grain initiative, which the Kremlin pulled out of six weeks ago.
The deal — brokered by the United Nations and Turkey in July 2022 — had allowed nearly 33 million metric tons (36 million tons) of grain and other commodities to leave three Ukrainian ports safely despite Russia’s war.
However, Russia broke away from the agreement after claiming that a parallel deal promising to remove obstacles to Russian exports of food and fertiliser hadn’t been honoured.
Moscow complained that restrictions on shipping and insurance hampered its agricultural trade, even though it has shipped record amounts of wheat since last year.
The Sochi summit follows talks between the Russian and Turkish foreign ministers on Thursday, during which Russia handed over a list of actions that the West would have to take in order for Ukraine’s Black Sea exports to resume.
Erdogan has indicated sympathy with Putin’s position. In July, he said Putin had “certain expectations from Western countries” over the Black Sea deal and that it was “crucial for these countries to take action in this regard.”
Elsewhere in Ukraine, three people were killed in two separate attacks by Russian shelling in the Donetsk area Sunday. An 85-year-old man was named among the victims after being crushed by the rubble of his own home, Ukraine’s Prosecutors’ Office reported.
A 36-year-old man was also killed in another Russian attack on Ukraine’s Kherson region.
Ukrainian prosecutors announced Sunday that they had opened a war crimes investigation into the death of a police officer killed by Russian shelling on the town of Seredyna-Buda on Saturday afternoon.
Two other police officers and one civilian were wounded during the attack, which hit Ukraine’s north-eastern Sumy region.
