Abstract. Important parameters of interaction between Turkey and Turkmenistan are the growth of mutual trade, investment cooperation, Turkmen labor migration, and the promotion of Turkish “soft power” in the humanitarian sphere. Ethnic community has become the main factor in the rapprochement of the two countries and the actualization of the issue of Turkmenistan’s accession to the Organization of Turkic States (OTS). Despite pressure from Ankara, Turkmenistan, adhering to the status of neutrality and not becoming a full member of the OTS, actively cooperates with the structures that are part of the organization. Further rapprochement between the two countries is facilitated by joint projects in the field of transit of Turkmen gas through Turkey to Europe and the creation of new transport corridors.
