Global AI Governance: Where the Challenge is the Solution- An Interdisciplinary, Multilateral, and Vertically Coordinated Approach

Current global AI governance frameworks struggle with fragmented disciplinary collaboration, ineffective multilateral coordination, and disconnects between policy design and grassroots implementation. This study, guided by Integration and Implementation Science (IIS) initiated a structured interdisciplinary dialogue at the UN Science Summit, convening legal, NGO, and HCI experts to tackle those challenges. Drawing on the common ground of the experts: dynamism, experimentation, inclusivity, and paradoxical governance, this study, through thematic analysis and interdisciplinary comparison analysis, identifies four core principles of global AI governance. Furthermore, we translate these abstract principles into concrete action plans leveraging the distinct yet complementary perspectives of each discipline. These principles and action plans are then integrated into a five-phase, time-sequential framework including foundation building, experimental verification, collaborative optimization, global adaptation, and continuous evolution phases. This multilevel framework offers a novel and concrete pathway toward establishing interdisciplinary, multilateral, and vertically coordinated AI governance, transforming global AI governance challenges into opportunities for political actions.
