ANKARA- Turkish President Tayyip Erdogan will visit Russia's Sochi on November 13, followed by a visit to Kuwait the following day, his office said on Monday.

The visit to Sochi comes amid reports of potential sticking points in Turkey's planned purchase of a Russian S-400 surface-to-air missile system, and Turkish objections to the attendance of Syrian Kurdish groups to a Russian-sponsored Syrian peace congress scheduled for Nov. 18.

Last week, the two countries took a step towards the solution of an import crisis as Russia lifted restrictions on import of Turkish tomatoes.
