Russia's deputy UN ambassador said that he was not ''optimistic'' about the renewal of a deal brokered by Türkiye and the UN that allows Ukrainian grain and fertilizer exports.

“It depends what we get from this deal. So far, we’ve gotten very little,” Dmitry Polyanskiy told Anadolu Agency. “I would not be too optimistic at this stage,'' Anadolu Agency reports. “The things that were promised to us are not being implemented...We want our part of the deal to be implemented,” he said.

Russian authorities have complained that Western sanctions ''indirectly'' hinder the country’s grain and fertilizer exports despite the deal. “There are indirect effects of the sanctions. There is over-compliance from Western companies, and there is a clear undesire of Western countries to rectify this situation,” said Polyanskiy.

The deal was initially signed for 120 days and expires in November. The United Nations is seeking to extend and expand the Ukraine grain deal for a year. UN spokesperson Stephane Dujarric said on Oct. 17 that discussions will continue on extending and expanding the grain deal, also known as the Black Sea Grain Initiative.

Türkiye, the UN, Russia and Ukraine signed a landmark deal on July 22 to reopen three Ukrainian ports -- Odesa, Chornomorsk and Yuzhny -- for grain that had been stuck for months because of the ongoing Russia-Ukraine war to address a global food crisis.
