Introduction. It has been almost thirty years since the idea of forming Eurasian space was voiced and seven years since that idea was embodied in the establishment of the Eurasian Economic Union (EAEU). Despite the acknowledgment of the EAEU importance and the recognition of the need of its further development by its member states, the organisation’s future is still in question. For instance, an increase in barriers has been observed, despite the fact that at the very beginning in 2015 when the EAEU was established, a gradual creation of the Eurasian customs union without exceptions and restrictions was proclaimed as one of its principles. Internal problems emerging between the EAEU member states considerably slow down the EAEU activity both within the EAEU and with its partners, and require a discussion of a broader agenda that goes beyond the economic sphere. In this regard, the authors set the goal of researching approaches to further development of the Eurasian economic integration as well as the harmonization of the EAEU member states in socio-cultural area. During the research, the authors used methods of scientific cognition, consistency, analysis and legal comparison. In order to examine the EAEU bodies’ development the authors also used legal research. Results. The authors’ position substantiated in the work is based on the history of the development of Eurasian economic integration, the influence of foreign policy, internal factors and soft power carried out by the neighboring countries of the region in various socioeconomic spheres. Conclusions. As a result of the research, the authors come to the conclusion that it is necessary to restore and deepen cultural and historical ties between the participants of the Eurasian Economic Union, as a separate area of activity of the Eurasian Economic Commission.
