MOSCOW (Sputnik) — According to the FSMTC statement, the meeting was held on December 12-14, and resulted in signing of a protocol, whose details have not been disclosed.
Russian-Turkish relations deteriorated after the downing of a Russian military plane by a Turkish fighter jet in Syria on November 24, 2015. Moscow imposed a number of restrictive measures on Turkey in response to what President Vladimir Putin then described as a "stab in the back." A thaw in relations between Moscow and Ankara began in June following Turkey's apology to Russia.
