Abstract. The article explores integration processes in the Eurasian space, including the development of the Eurasian Economic Union (EAEU) and the Organization of Turkic States (OTS). The author emphasizes the importance of the EAEU as an institutionalized integration organization and describes the growing influence of the OTS, as well as its role in promoting cultural, humanitarian, and economic cooperation. The competition between Eurasian and Turkic integration formats and Kazakhstan's unique role, which supports a flexible foreign policy and actively participates in both structures, is highlighted. The article provides a comparative analysis of these integration entities and discusses the achievements in advancing Turkic integration. Specifically, it highlights the creation of a simplified customs corridor and the Turkic Investment Fund. Special attention is given to Kazakhstan's positioning as a proactive middle power, promoting its national interests through economic cooperation and integration.
