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.

As artificial intelligence increases in popularity, many countries have expressed security concerns regarding the technology. The potential use of nuclear weapons falls into this category. Officials from the United States have called on other nuclear powers to commit to an understanding that artificial intelligence would never be authorized to approve the use of nuclear weapons

Russia on Wednesday vetoed a United Nations resolution that would ban the use of nuclear weapons in outer space amid US intelligence-backed concerns that Moscow is trying to develop a nuclear device that can destroy satellites.
