This article examines the close relationship between national development and foreign policy within the framework of the 20-year vision document of the Islamic Republic of Iran. In this document, Iran is defined as a developed country with a leading economic, scientific, and technological position in the region and active interaction with the global economy. The article analyzes three development models (introverted, extroverted, mixed) and shows that Iran has moved towards extroverted (export-oriented) development after the imposed war. This model requires an interactive foreign policy and active diplomacy to benefit from global resources and is not compatible with isolationism. A developmental foreign policy must be consistent with the development model, present a positive image of Iran, gain international credibility, and prevent Iran’s position from becoming securitized. This policy is based on peaceful coexistence, de-escalation, trust-building, and multilateralism, and while maintaining national independence and security, it facilitates sustainable development and constructive global interaction. The research question is: How does a developmental foreign policy contribute to the national development goals in the Vision Document? The research hypothesis states that an outward-oriented and interactive foreign policy, by creating a suitable platform for taking advantage of global opportunities and preventing Iran's position from becoming securitized, contributes to the realization of the goals of the Vision Document, including regional primacy, while maintaining independence and national security.
