Turkish President Tayyip Erdogan said after talks with Russia’s Vladimir Putin on Monday that it would soon be possible to revive the grain deal that the United Nations says helped to ease a food crisis by getting Ukrainian grain to market.

Russia quit the deal in July — a year after it was brokered by the United Nations and Turkey — complaining that its own food and fertilizer exports faced serious obstacles.

Erdogan, who previously played a significant role in convincing Putin to stick with the deal, and the United Nations are both trying to get Putin to return to the deal.

Erdogan said that Russia’s expectations were well-known to all and that the shortcomings should be eliminated, adding that Turkey and the United Nations had worked on a new package of suggestions to ease Russian concerns.
