Talks on the establishment of a grain corridor were held in Istanbul on July 13. They were attended by military delegations from Russia, Turkey, Ukraine, and representatives from the United Nations. UN Secretary General Antonio Guterres said after the meeting that it was a major step toward ensuring safe and reliable food export from Ukraine across the Black Sea.
