This article examines the interdependence of state and regional security in the modern globalized world, characterized by a combination of classical realist and liberal views on international relations and the conduct of international politics. The work analyzes the role of regional cooperation for ensuring the security of the state and both the regional and global systems using the example of the Shanghai Cooperation Organization (SCO) and its member states: Russia, China, Kazakhstan, Tajikistan, Kyrgyzstan and Uzbekistan. The scope of the study is limited to the interactions of the original SCO members, as well as a five-year period (from 2020 to 2024). It is based on such general logical methods as the analysis of offi cial media and SCO sources to determine the frequency of bilateral meetings of state representatives, as well as the intensity of interaction between member states within organization. The abstraction is used to visualize the obtained quantitative results. The analysis of the sources, according to the number of signifi cant contacts of the SCO states was conducted according to “Heads of State”, “Heads of Government”, “Heads of Foreign Aff airs Agencies” interactions. The analysis of bilateral contacts of the SCO states under consideration was conducted within the following directions: “President”, “Parliament”, “Government”, “MFA” based on open sources in the media. The study develops recommendations for increasing the effi ciency and productivity of regional security organizations, which are relevant for a modern multi-level, comprehensive approach to solving global and regional challenges within the established security architecture.
