A senior U.S. official on Thursday urged China and Russia to match declarations by the United States and others that only humans, and never artificial intelligence, would make decisions on deploying nuclear weapons.
State Department arms control official Paul Dean told an online briefing that Washington had made a "clear and strong commitment" that humans had total control over nuclear weapons, adding that France and Britain had done the same.
"We would welcome a similar statement by China and the Russian Federation," said Dean, principal deputy assistant secretary in the Bureau of Arms Control, Deterrence and Stability.
