The developments that have taken place in recent decades have greatly expanded the connection and solidarity between geographical spaces. In a way that geographical spaces cannot maintain their sustainability without action and interaction with each other and are faced with challenges and problems. Among the main links of this connection between geographical spaces, including countries, are communication corridors in their various forms and types. Communication corridors in this interconnected world have connected and compressed time and space in various ways. Among the outputs of these corridors, one can mention the increase in the dependence of countries on each other, which in itself strengthens and increases peace and security between them. In the meantime, Peace, traditionally understood as the absence of war, has evolved into a broader concept encompassing justice, human rights, and societal harmony, as articulated by Johan Galtung’s framework of negative, positive, structural, and cultural peace. In the contemporary geopolitical landscape, peace extends beyond non-violence to foster cooperation and mutual prosperity. Geopolitics, historically tied to power struggles, has shifted toward facilitating peace and development, with communication corridors emerging as critical tools for spatial integration and conflict reduction. These corridors, encompassing road, rail, air, and energy routes, transcend mere transportation, acting as synergistic infrastructures that enhance economic interdependence, cultural exchange, and diplomatic stability. Iran and Turkey, as key regional powers in West Asia with a 500-km shared border and rich historical ties, offer a compelling case for studying how such corridors can transform competitive dynamics into cooperative frameworks. Despite political differences, their shared infrastructure projects, like the Islamabad-Tehran-Istanbul (ITI) corridor and the Tabriz-Ankara gas pipeline, underscore their potential to foster sustainable peace. This study explores how these corridors contribute to positive peace by reducing geopolitical tensions and promoting regional stability.
