Leaders meet at Apec summit in Peru for what is expected to be last time before Donald Trump assumes US presidency

Joe Biden met with Xi Jinping on Saturday afternoon, coming to the agreement that human beings and not artificial intelligence should make decisions over the use of nuclear weapons, according to the White House.

In what is believed to be the last meeting between the two leaders before Donald Trump assumes the US presidency, the two met at a hotel on the sidelines of the annual Asia-Pacific Economic Cooperation summit in Peru, where they shook hands before each delivering opening remarks on the China-US relationship.
