In an era defined by a polycrisis of interconnected challenges—from the escalating climate crisis and global health emergencies to deepening geopolitical fissures—traditional diplomatic tools are often insufficient. This article posits that science diplomacy is increasingly recognized not merely as a niche area of foreign policy but as a critical instrument for navigating complexity and fostering global cooperation. It provides a comprehensive analysis of the field, tracing its evolution and dissecting its core conceptual frameworks, notably the tripartite model of ‘science in diplomacy,’ ‘diplomacy for science,’ and ‘science for diplomacy,’ while also engaging with critical theories that illuminate the structural inequalities embedded within these dynamics. The paper examines the operational dynamics through which it functions, from formal intergovernmental agreements and large-scale research infrastructures to the resilient informal networks of scientists that often persist despite political tensions. Through a detailed analysis of illustrative case studies—including CERN as a model for post-conflict reconciliation, the SESAME light source as a beacon of cooperation in the Middle East, the dual-edged lessons of the COVID-19 pandemic, and Morocco’s strategic use of science for regional leadership—the article explores both the potential and the limitations of these approaches in practice. The central thesis argues that while science diplomacy is not a panacea, it offers a vital pathway for building transnational networks grounded in trust and evidence, thereby contributing to more effective global governance. However, its success is continually challenged by the inherent tension between the universalist ethos of science and the competitive realities of national interests, as well as by the often-unseen power asymmetries inherent in global scientific collaboration. The article concludes that building greater capacity, consciously addressing these power dynamics, and navigating this ‘interest paradox’ are essential for leveraging science diplomacy to address the defining global challenges of the 21st century.
