This study focuses on the feasibility of economic convergence in the Persian Gulf region (including Iran, Saudi Arabia, Iraq, Qatar, the United Arab Emirates, Oman, Kuwait, and Bahrain) and the requirements for achieving it. Economic convergence is considered a process aimed at attaining peace, security, and sustainable development in the region. Accordingly, the central question of this research is: How can Persian Gulf countries achieve economic convergence to promote peace, security, and sustainable development? The study hypothesizes that, to achieve these goals, countries in the region must leverage a combination of economic, political, security, and socio-cultural-religious capacities, while overcoming divergent factors, and adopt behavioral and policy measures that integrate economic convergence into national decision-making and foreign policy. The research employs a mixed-methods approach, combining qualitative document-based analysis with quantitative and statistical methods. Ultimately, the study proposes a comprehensive network model for achieving peace, security, and sustainable development through economic convergence in the Persian Gulf. This model rejects hierarchical prioritization of indicators and emphasizes the simultaneous utilization of multiple economic, political, security, and socio-cultural-religious components to achieve economic convergence.
