Biden and Xi reach agreement to restrict AI in nuclear weapons decisions
President Biden and China’s leader Xi Jinping agreed to take a first step on limiting AI control over nuclear weapons.

President Joe Biden and China’s President Xi Jinping held a two-hour meeting on the sidelines of the APEC summit on Saturday. Both leaders reached a significant agreement to prevent AI from controlling nuclear weapons systems and made progress on securing the release of two US citizens wrongfully detained in China. Biden also pressured Xi to reduce North Korea’s support for Russia in the ongoing Ukraine conflict.
The breakthrough in nuclear safety, particularly the commitment to maintain human control over nuclear decisions, was reported as an achievement for Biden’s foreign policy. Xi, in contrast, called for greater dialogue and cooperation with the US and cautioned against efforts to contain China. His remarks also acknowledged rising geopolitical challenges, hinting at the difficulties that may arise under a Trump presidency. The meeting showcased a shift in tone from their previous encounter in 2023, reflecting a more constructive dialogue despite underlying tensions.
Reuters reported that it remains uncertain whether the statement will result in additional talks or concrete actions on the issue. The US has long held the position that AI should assist and enhance military capabilities, but not replace human decision-making in high-stakes areas such as nuclear weapons control. Last year, the Biden-Harris administration announced the Political declaration on responsible military use of AI and autonomy, and more than 20 countries endorsed the declaration. The declaration specifically underlines that “military use of AI capabilities needs to be accountable, including through such use during military operations within a responsible human chain of command and control”.
