Turkish President Tayyip Erdogan will discuss a new mechanism to allow Ukrainian grain exports through the Black Sea with his Russian counterpart Vladimir Putin during his upcoming visit to Turkey, Foreign Minister Hakan Fidan said on Sunday. Putin is expected to visit Turkey on Feb. 12 to meet Erdogan, a Turkish official previously said, in what will be the Russian leader's first trip to a NATO ally since Moscow's invasion of Ukraine in February 2022.
