‘Silent Cold War’: Why calls to slow AI have sparked new US–China frontier
Anthropic’s CEO urged a pause on AI progress, citing catastrophic risks and a potential Chinese lead. China rebuked the move as fear‑mongering, while the US remains committed to its technological edge. The clash underscores a growing AI Cold War between the two powers.
On Saturday, Dario Amodei, the chief executive of Anthropic, a prominent U.S. artificial‑intelligence firm, publicly warned that the rapid pace of AI development could soon pose catastrophic threats to humanity. In an essay released over the weekend, Amodei called for a deliberate slowdown in the creation of the most powerful AI systems and urged Washington to restrict China’s access to advanced chips and technology.
Why the alarm is sounding
Amodei’s concerns stem from the accelerating rate at which AI models are becoming more capable. He cautioned that within six to twelve months a “swarm” of AI agents could potentially take over the internet, creating a persistent botnet that might inflict billions of dollars in damage. He added that the scale of harm would grow as models become more powerful without adequate safeguards. The warning was echoed by other industry leaders, including OpenAI’s Sam Altman and SpaceX founder Elon Musk, who have all expressed unease about the speed of progress.
Beyond safety, Amodei highlighted the geopolitical dimension of the debate. He argued that a Chinese lead in AI would pose a grave danger to the United States and the world. To that end, he urged the U.S. government to maintain restrictions on the export of cutting‑edge AI chips and chip‑making equipment to China, and to take action against the alleged “distillation” of U.S. models by Chinese laboratories.
China’s response and the “silent Cold War” narrative
China’s Foreign Ministry quickly denounced the call for a slowdown as “fear‑mongering.” Spokesperson Guo Jiakun called the proposal a “Cold War playbook” designed to curb Chinese AI development and preserve U.S. technological dominance. The state‑backed Global Times went further, labeling the move a hypocritical and short‑sighted attempt to maintain an advantage in a field that is increasingly global.
China’s stance is rooted in its broader strategy to pursue an “open, inclusive and benevolent” approach to AI. Beijing argues that confrontational tactics and malicious competition only disrupt the global governance of artificial intelligence. The Chinese government has also warned against giving algorithms the power to “determine life and death,” especially in military contexts.
The current state of the US‑China AI race
According to the 2026 AI Index Report from Stanford University, U.S. companies invested $285.9 billion in AI in 2025, compared with $12.4 billion in China. American firms still dominate the private investment and production of leading AI models. However, Chinese companies have demonstrated resilience, producing competitive models even under U.S. restrictions on advanced chips.
For instance, DeepSeek, a Chinese AI startup, announced a model that could be trained for less than $6 million worth of Nvidia H800 chips, a fraction of the multi‑billion‑dollar budgets of U.S. giants like OpenAI and Google. This development sent shock waves through the AI community and highlighted China’s ability to innovate with limited resources.
Both sides have imposed hostile policy measures on each other. The U.S. has restricted China’s access to advanced semiconductors and chip‑making technology, citing national security concerns. Meanwhile, China has tightened export controls on five critical rare‑earth metals and on equipment used to refine them, while leveraging its advantage in energy production to power large AI data centers.
Military implications and global concerns
AI’s military applications have become a point of contention. The U.S. has accelerated the use of AI across intelligence and warfighting domains, while the Pentagon has clashed with Anthropic over the use of its models for autonomous weapons or mass surveillance. China has criticized the expanding military use of AI, warning against algorithms that could decide life and death.
Reports have shown that Chinese military‑linked researchers have used outputs from leading U.S. AI models to enhance surveillance and defense capabilities. Meanwhile, U.S. tech companies have supplied cloud and AI technology to Israel’s defense establishment, raising concerns about the use of AI in conflicts such as the Gaza war.
What’s next for the AI race?
Calls for a slowdown in AI development raise questions about the industry’s ability to manage the technology responsibly. Aya Ibrahim, a senior visiting fellow at the AI Now Institute, warned that the race narrative could drive companies to prioritize speed over safety, potentially leading to a “race to the bottom.” She emphasized the need for a more thoughtful approach that balances innovation with ethical considerations.
As the U.S. and China continue to compete over AI capabilities, the world watches closely. The debate over safety, national security, and technological dominance is likely to shape policy decisions, investment strategies, and the future trajectory of artificial intelligence worldwide.
Why it matters
The debate highlights how AI’s rapid growth intersects with national security and global power dynamics, potentially reshaping international relations and the future of technology governance.
Key points
- Anthropic CEO calls for AI slowdown citing catastrophic risks

- U.S. leads in AI investment but China shows resilience
- Both nations impose export controls on advanced chips and rare earths
- AI’s military applications raise ethical and security concerns
Frequently asked questions
Why is the U.S. restricting AI chips to China?
The U.S. limits advanced chip exports to China to prevent potential military and intelligence gains that could threaten national security.
What does a “slowdown” in AI development mean?
It refers to deliberate measures to pace the creation of powerful AI models, giving governments and researchers time to assess risks and implement safeguards.
How is China responding to U.S. restrictions?
China has tightened export controls on critical rare‑earth metals and equipment, while emphasizing an open and inclusive approach to AI development.
