In the era of globalization and growing interdependence, regional and international integration has become an essential component of state development strategies. For the Republic of Tajikistan, located in a strategically important area of Central Asia and possessing significant hydropower and natural resources, integration serves as a key factor for ensuring economic progress, national security, and international recognition. After independence, Tajikistan adopted a foreign policy centered on balanced cooperation and mutual benefit, as defined in the *Foreign Policy Concept of the Republic of Tajikistan* (2015) [1]. The country actively participates in major regional projects, such as CASA-1000, enabling the export of over 40 billion kWh of renewable electricity annually (World Bank Report, 2023) [2]. Tajikistan’s role in regional organizations, including the CIS, SCO, ECO, and OSCE, demonstrates its commitment to strengthening security, economic cooperation, trade, and environmental sustainability. Scholars highlight the significant role of Tajikistan in regional energy, water diplomacy, and security initiatives [3,87; 4,56; 7,58; 9,45]. Furthermore, Tajikistan contributes to global integration through active cooperation with the UN, WTO, World Bank, and other international institutions, solidifying its diplomatic standing and fostering sustainable development [10; 11]. This article analyzes the role of Tajikistan in regional and international integration processes, emphasizing its strategic geopolitical position, multidimensional foreign policy, and contribution to regional stability and global initiatives.
