Artificial Intelligence (AI) is transforming the field of International Relations (IR) by reshaping diplomacy, security, and global governance. This article employs a descriptive-analytical methodology, systematically reviewing and synthesizing existing literature to analyse AI’s applications and implications in IR. It explores AI’s potential to enhance diplomatic decision-making through predictive analytics and automated negotiation systems, as well as its applications in cybersecurity and military technologies. The article also highlights the ethical and regulatory challenges posed by AI, such as algorithmic bias, weaponization, and disparities in global access to AI technologies. While AI offers innovative solutions for global challenges, such as climate change and public health, its integration into the global system demands robust international frameworks and ethical safeguards. Recommendations include promoting equitable AI access, fostering international cooperation, and leveraging AI for peacebuilding and sustainable development. This article contributes to the growing discourse on the intersection of AI and IR, emphasizing the need for responsible and inclusive global governance.
