Introduction
Complex geopolitical dynamics, security rivalries, and extra-regional interventions have historically shaped Iran’s interaction with the Persian Gulf countries. Since the 1979 Islamic Revolution, attempts at regional cooperation have often been undermined by the Arab Gulf states’ security-oriented perceptions and the lack of sustained engagement in functional areas. Among the underexplored domains in this context is nuclear medicine—a field in which Iran has developed a significant comparative advantage through technological innovation, infrastructure investment, and domestic radiopharmaceutical production. Meanwhile, the member states of the Gulf Cooperation Council (GCC) are increasingly facing public health challenges, particularly a rising burden of non-communicable diseases (NCDs) such as cancer, which require affordable and high-precision diagnostic and therapeutic solutions.
Research Question(s)
How can Iran’s nuclear medicine capacities—particularly in radiopharmaceutical production and medical technology infrastructure—effectively advance economic diplomacy with the Persian Gulf states? To what extent can this form of functional engagement reshape regional dynamics according to the theory of functionalism?

Literature Review

The existing literature reveals four dominant trends:
2.1. Iran’s Nuclear Program and Security Discourses
Most previous studies—such as Emami (2005)—have centered on the military and security implications of Iran’s nuclear program, largely neglecting its peaceful and medical applications, including nuclear medicine.
2.2. Economic Convergence and Strategic Challenges
Bidalehkhani and Kalmarzi (2015) argue that limited economic cooperation has hindered political convergence among Persian Gulf states. They propose that shared economic interests, including in peaceful nuclear technologies, could help reduce tensions and foster integration.
2.3. Public Diplomacy and Scientific Exchange
Brimani and Hojvani (2017) highlight the role of apolitical scientific collaboration in improving Iran’s regional image. This approach is particularly relevant to the context of nuclear medicine diplomacy.
2.4. Economic Diplomacy and Technological Leverage
Heidari and Enami Alamdari (2012) emphasize the strategic deployment of advanced technologies—including nuclear medicine—as tools of economic diplomacy, especially in the face of international sanctions.
 Methodology
This study adopts a mixed-methods approach:
- Qualitative analysis: Involving semi-structured interviews with health policymakers, experts in nuclear medicine, and regional affairs analysts.
- Quantitative analysis: Including GCC cancer prevalence data, cost comparisons, trade statistics in radiopharmaceuticals, and infrastructure indicators.
Triangulation of these methods ensures a robust analysis of both structural opportunities and limitations.
Results
Iran has attained full self-sufficiency in radiopharmaceutical production and currently operates 155 nuclear medicine centers, establishing itself as a regional frontrunner in the field. It ranks second in the MENA region in terms of nuclear medicine capabilities and 17th globally in medical science research output. In contrast, GCC countries such as Saudi Arabia and the United Arab Emirates face significant deficits in both infrastructure and specialized human resources in this sector. This asymmetry creates a strategic opening for Iran to export its expertise, services, and technologies, paving the way for functional interdependence and deeper regional engagement.
Discussion
Drawing on Mitrany’s theory of functionalism, this study posits that technical cooperation in the health sector, particularly in high-demand, low-politicized domains such as nuclear medicine, can generate positive spillover effects, facilitating broader regional collaboration. To operationalize this potential, the following policy instruments are proposed:
Establishing regional distribution networks for radiopharmaceuticals to reduce delivery delays and enhance therapeutic effectiveness.
Creating joint ventures in diagnostic imaging and isotope production facilities, particularly in cooperation with politically neutral actors such as Oman.
Promoting medical tourism, targeting GCC cancer patients seeking affordable, high-quality treatment services in Iran.
Launching educational exchange programs to train GCC health professionals in Iranian institutions, fostering both capacity building and durable partnerships.
Advancing regional health diplomacy through cooperative initiatives under international frameworks, such as those led by the International Atomic Energy Agency (IAEA).
However, several structural and political challenges remain. Chief among them are the adverse effects of international sanctions on logistics and technology transfer, growing competition from foreign providers, such as South Korea’s active presence in the UAE, and infrastructural limitations that constrain Iran’s capacity to scale up exports.
Conclusion
This study concludes that nuclear medicine represents a strategic and low-risk avenue for advancing Iran’s economic diplomacy in the Persian Gulf. By capitalizing on its scientific expertise and infrastructural advantages, Iran can help reframe the prevailing threat-based narrative into one centered on functional cooperation. Engagement in this sector offers not only immediate health-related benefits but also a platform for sustained regional integration. However, realizing this potential requires coordinated strategic investment, active international engagement, and alignment with broader diplomatic initiatives.
