US President Joe Biden and Chinese counterpart Xi Jinping will attend the first day of an Asia-Pacific leaders' summit Friday ahead of a face-to-face meeting under a cloud of diplomatic uncertainty cast by Donald Trump's election victory.

Chinese President Xi Jinping arrived in Peru Thursday for an Asia-Pacific summit where he will meet US counterpart Joe Biden under the shadow of a looming trade war with the incoming administration of Donald Trump.

President Joe Biden is planning to meet Saturday with Chinese President Xi Jinping during a trip to Lima, Peru, according to White House officials, in what amounts to a final meeting between two leaders of superpowers amid a period of significant transition that could alter that relationship.
