The Turkish president, Recep Tayyip Erdoğan, has concluded face-to-face talks with Vladimir Putin by claiming a deal to export Ukrainian grain through the Black Sea could be revived.
But there was no evidence of a breakthrough as the Russian leader again accused the west of reneging on promises.
Putin claimed there had been no crisis in global grain markets since Moscow pulled out of the deal two months ago over what it said was the west’s failure to keep its side of the bargain covering Russian food and fertiliser exports. He said prices were falling and there was no evidence of food shortages.
