Russian President Vladimir Putin signaled that Moscow would not extend the Ukraine grain deal as he said none of Moscow's demands had been met.

"I want to emphasize that nothing was done, nothing at all. It's all one-sided," Putin said in a televised interview Thursday, adding that "We will think about what to do, we have a few more days."

Putin also said the United Nations had so far failed to come up with a satisfactory solution to the issue and he denied having received any letter containing proposals from the U.N. Secretary-General.

"We can suspend our participation in the deal, and if everyone once again says that all the promises made to us will be fulfilled, then let them fulfill this promise. We will immediately rejoin this deal," Putin said.

A Kremlin spokesperson later clarified that Russia had not taken a final decision on whether to exit the grain deal.

The U.N. and Türkiye brokered the Black Sea Grain Initiative with Russia and Ukraine in July 2022 to help alleviate a global food crisis that worsened after Moscow sent forces into Ukraine and blockaded Ukrainian ports.

To convince Putin to agree to the deal, U.N. officials also agreed to help Russia get its food and fertilizer exports to foreign markets – something Moscow says they have failed to do.

While Russian exports of food and fertilizer are not subject to Western sanctions imposed over Russia's military campaign in Ukraine, restrictions on payments, logistics and insurance have amounted to a barrier to shipments for Moscow.

Sources told Reuters that U.N. Secretary-General Antonio Guterres had written to Putin suggesting that Moscow allow the deal to continue for several months to give the European Union time to connect a subsidiary of the Russian Agriculture Bank (Rosselkhozbank) to the international payment network SWIFT.

Putin said on Thursday he had not received any such message.
