The leaders agreed that humans should control decisions to use nuclear weapons — not AI. And they talked about the importance of stability during the transition to a new U.S. administration.

Before the meeting with Xi, Biden’s aides said he planned to confront the Chinese leader over China’s threats against Taiwan, its human rights violations and its support for Russia in Putin’s war in Ukraine. Biden also planned to urge Xi to discourage North Korea from continuing to support Russia in that conflict.
