Turkish President Tayyip Erdogan will visit Russia's Black Sea resort of Sochi soon and there may be developments regarding the deal that allowed the maritime export of Ukrainian grain, a spokesperson for Erdogan's ruling AK Party said on Monday.

The UN- and Turkey-brokered grain deal ended after Moscow quit last month. Ankara has been trying to persuade Russia to return to the agreement, under which Odesa's three seaports shipped tens of millions of tons of grain during Russia's invasion.

Omer Celik, the party spokesperson, did not specify whether Erdogan would meet with Russian President Vladimir Putin but the Kremlin said on Friday that there is an understanding the two will meet in person soon.
