US, China Skip Joint AI Warfare Pledge As Global Divide Deepens

Artificial intelligence (AI) is increasingly influencing military strategies and capabilities worldwide, prompting urgent discussions on how to govern its use in warfare. Recently, at the REAIM summit held in Spain, 85 nations convened to address this critical issue. A key outcome was a non-binding declaration aimed at setting principles for the military application of AI. However, the United States and China, two of the world’s leading powers in AI development and military technology, notably declined to sign the declaration. This decision underscores the widening global divide on regulating AI in military contexts amid escalating geopolitical tensions.

The declaration sought to establish guidelines promoting responsible use of AI in warfare, emphasizing transparency, accountability, and the minimization of unintended harm. Despite these goals, only 35 of the 85 participating countries endorsed the principles, reflecting significant disagreements on the scope and enforceability of such regulations. The reluctance of the US and China to commit signals their preference to maintain strategic flexibility and control over AI advancements without external constraints. Both nations are heavily investing in AI-driven military capabilities, viewing them as critical to future defense and deterrence strategies.

This split highlights broader challenges in international arms control efforts related to emerging technologies. Unlike traditional weapons, AI systems can be rapidly developed and deployed, often with dual-use applications that complicate regulation. The absence of consensus between major powers complicates efforts to establish universal norms or treaties governing AI in warfare. Moreover, the geopolitical rivalry between the US and China exacerbates mistrust, making cooperative frameworks difficult to achieve. Other countries face pressure to align with one side or the other, further fragmenting global consensus.

The implications of this divide are profound. Without agreed-upon standards, the risk of AI-driven arms races and unintended escalations increases. Autonomous weapons systems, AI-enabled decision-making, and cyber warfare capabilities could be deployed with limited oversight, raising ethical and security concerns. The failure to secure broad commitments at the REAIM summit suggests that international governance of military AI remains in its infancy. Future diplomatic efforts will need to address the competing interests of major powers while fostering transparency and confidence-building measures.

In summary, the US and China’s refusal to endorse the REAIM summit’s AI military use declaration reflects deep geopolitical and strategic divides. While many nations support establishing norms for AI in warfare, the lack of consensus among key players limits the effectiveness of such initiatives. As AI continues to transform military capabilities, the international community faces urgent challenges in balancing innovation, security, and ethical considerations. The path forward will require sustained dialogue, trust-building, and potentially new frameworks that can accommodate the complex realities of AI in global security.
