The first ships with Ukrainian grain will depart from the Black Sea ports in the near future after the recent signing of a landmark grain exports deal, RIA news agency reported on Wednesday, quoting Russian Deputy Foreign Minister Andrei Rudenko.

The remarks came after a Turkish official said that the first exports were likely to happen this week. 

"It will not take more than a few days. It looks like the first grains will be loaded this week and its export from Ukraine will take place," the Turkish official, who requested anonymity, was quoted by Reuters on Wednesday. 

But Rudenko said that the deal to unblock Ukrainian grain exports on the Black Sea could collapse if obstacles to Russia's agricultural exports are not promptly removed.

On July 22, Russia and Ukraine signed a deal brokered by Ankara and the United Nations to reopen grain and fertilizer exports.
