Transit Rivalry Or Partnership? INSTC Vs. Middle Corridor In Central Asia

The Middle Corridor and the International North-South Transport Corridor (INSTC) represent two significant transcontinental trade routes shaping Eurasian connectivity. Both corridors aim to diversify trade flows, reduce dependency on traditional maritime routes, and enhance economic integration. However, their overlapping geographic reach in Central Asia has raised questions about whether they are rivals competing for influence or potential partners fostering regional connectivity. This article examines the geopolitical, economic, and infrastructural dimensions of these corridors, analyzing their respective strengths, challenges, and strategic priorities. By assessing the interests of key stakeholders such as Russia, Iran, Turkey, and China, the study highlights areas of competition, including access to transit hubs and trade facilitation policies, as well as opportunities for collaboration, such as shared infrastructure and mutual reduction of logistical costs. The findings underscore the corridors' complementary potential in driving sustainable development and enhancing Eurasia's strategic role in global trade, provided regional and international actors prioritize cooperative frameworks over zero-sum competition.
