The role of transport corridors in strengthening regional cooperation in Centra l Asia is critical, especially in the context of Iran's evolving foreign policy. Amidst the backdrop of the Russian-Ukrainian confrontation and the expansion of major infrastructure projects like the International North-South Transport Corridor (INSTC), Iran's strategic initiatives in Central Asia have gained prominence. This article aims to explore how transport corridors can enhance Iran's regional influence and cooperation with Central Asian countries. The main question addressed is: how do these transport corridors contribute to regiona l stability and economic integration? The hypothesis is that Iran's active participation in developing these corridors, particularly through key projects like the Chabahar Port, not only boosts trade and connectivity but also counters geopolitica l isolation and fosters long-term regional cooperation. The research utilizes the theory of regional integration and interdependence, supported by qualitative content analysis of documents, texts, and expert interviews related to regional transport strategies.The findings indicate that efficient transport infrastructure is fundamental for economic development and political stability in Central Asia. Iran's collaboration with Russia and China further amplifies the benefits of these corridors, providing a strategic counterbalance to Western influence. Ultimately, the study highlights that Iran's role in Central Asia is pivotal for broader regional integration and sustainable development.
