Abstract
The article examines the problems of functioning of the mechanism for ensuring the national security of the Republic of Kazakhstan as a participant in the Eurasian Economic Union. The activities of the EAEU as an international organization for regional economic integration are aimed at creating favorable conditions for the development and increasing the competitiveness of the economies of its member states. At the same time, a single economic space, a common external customs border, and the competence of supranational bodies of the Union lead to challenges and threats to the national security of its members. Effective counteraction to these challenges and threats is impossible without an effective mechanism for ensuring national security, which, under the conditions of Kazakhstan’s membership in the Union, is ensured not only at the national (domestic) level, but also at the international (at the EAEU level) levels. In the process of research, an idea was formed of the legal mechanism for ensuring the national security of the Republic of Kazakhstan under the conditions of membership in the EAEU, a systematic and comprehensive analysis of its basic elements was given, and shortcomings in the functioning of this mechanism that pose threats to the national security of the Republic of Kazakhstan were identified. The authors proposed recommendations for improving the mechanism for ensuring national security of Kazakhstan in order to respect national interests in the context of participation in integration processes.
