Following the contemporary globalization process, cities have gained a strong presence in world politics, and by connecting to international urban networks, they play an effective role in the common interests of themselves and other urban actors. The current research aims to investigate the requirements of forming an international union of cities around the Persian Gulf by strengthening city diplomacy in the region with the benefit of a descriptive-analytical method. In this regard, the background of economic and social relations and the region's current situation have been investigated using reliable sources and articles. Finally, the model of city diplomacy in the Persian Gulf region has been presented. The research findings show that the cities of this region have moved in the direction of divergence despite the presence of many convergence factors, and the formation of an international urban union in the region will play an effective role in increasing convergence and greater peace in the region.
