Without mentioning President-elect Donald Trump's name, Chinese President Xi Jinping appeared to signal his concern that Trump's protectionist rhetoric on the campaign trail could send the U.S.-China relationship into another valley.

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.

Chinese President Xi Jinping, meeting with outgoing U.S. President Joe Biden at the APEC summit in Lima, Peru, vowed to work with the incoming Trump administration while addressing a wide range of contentious issues. Talks covered Taiwan, trade, cybercrime, and North Korea, with Xi emphasizing stability amid a tense transition period.
