Iran's economic diplomacy, as a country with a distinct history of trade and governmental exchanges, holds significant capacities that can play a crucial role in the development of foreign trade and enhancing Iran's appeal as a global market. This study aims to design a comprehensive strategic marketing model based on Iran's economic diplomacy. Initially, using the grounded theory approach, through interviews with 17 experts from the Tehran Chamber of Commerce, related concepts were identified and coded into six main sections. Subsequently, a process model was designed to show the impact of economic diplomacy on marketing activities, demonstrating how the capacities in this field can be effectively utilized. The research results indicate that the formation of a specialized team consisting of experts in economic diplomacy and marketing strategies can greatly assist in analyzing marketing opportunities in global markets and formulating appropriate strategies for foreign trade development and attracting foreign investment. This framework can serve as a foundation for government and business decision-making in the domain of Iran's foreign trade and economy.
