A senior U.S. official has called on China and Russia to join the United States and others in committing to human control over nuclear weapons, excluding artificial intelligence from decision-making processes. Paul Dean, a State Department arms control official, emphasized the importance of this norm, noting that the U.S., France, and Britain have all made such declarations. Dean urged China and Russia to follow suit, highlighting the need for responsible behavior in the context of the P5, the five permanent members of the UN Security Council.
