Improving the Political Mechanisms of the CSTO in the Context of Cooperation with International Organizations: Challenges and Adaptation Paths

The relevance of this study stems from the need to develop effective models of interorganizational cooperation in the context of the global transformation of security systems and increasing instability in international relations. The CSTO, as a key actor in Eurasian security, is actively advancing its political mechanisms to integrate with international structures and build strategic partnerships aimed at strengthening collective security. The political mechanisms of the CSTO are viewed as a set of institutions, procedures, and instruments that ensure the coordination and implementation of collective decisions by member states in the fields of foreign policy and interorganizational interaction. The development of the CSTO's political mechanisms of interaction with other international and regional organizations is becoming particularly relevant in the context of the transformation of the global security system and increasing instability in neighboring regions.The aim of this article is to provide a comprehensive assessment of the CSTO’s political mechanisms, identify their strengths and weaknesses, and formulate recommendations for their improvement in light of current challenges.Materials and methods. The study is based on systemic, institutional, and comparative-legal approaches. The empirical basis includes official CSTO documents, minutes of international meetings, analytical reports, academic journal publications, and open-source data. The case study method is applied to analyze practical examples of the CSTO’s cooperation with international organizations.Results. The key challenges identified include institutional heterogeneity among member states, bureaucratic barriers, political pressure, and coordination difficulties in a multipolar environment. Successful cooperation cases with the UN, SCO, CIS, and ICRC are examined, demonstrating the Organization’s potential in maintaining regional stability and countering new threats. Strategic directions for improvement are substantiated, including the development of hybrid security tools and the strengthening of peacekeeping capacities. Conclusions. The adaptation of the CSTO’s political mechanisms is essential for its effectiveness and legitimacy in the international arena. Strengthening the Organization’s position requires systematic updates to its legal framework, enhanced coordination with global actors, and the introduction of innovative tools for responding to contemporary security threats. Recommendations aimed at strengthening institutional cooperation with the UN, modernizing political and legal instruments, integrating hybrid security mechanisms, and expanding the humanitarian dimension constitute the strategic foundation for the CSTO’s future development.
