Abstract. The article reveals Turkey’s new priorities after the events happened in the Nagorno-Karabakh conflict zone in October 2020. For the first time in the history dealing with  the settlement of ethno-political conflicts in the post-Soviet space, a precedent was created when Ankara, being not a post-Soviet country, but a regional power, got involved  in the  conflict and won. This dramatically changed the configuration of the entire Transcaucasus in the field of security, where, on the one hand, Armenia was involved in rivalry between Russia, Turkey and Iran, while on the other - Russia and Turkey launched competitive cooperation in the region.
