When President Joe Biden meets for the final time Saturday with his Chinese counterpart Xi Jinping, his aides say the moment will be ripe for reflection on a relationship that began more than a decade ago,

The two leaders had what could be their final meeting in a long relationship, but often seemed to be speaking more to the president-elect than each other.

Xi, who arrived in Lima on Thursday, plans a week-long diplomatic blitz in Latin America that includes a refurbished free-trade agreement with Peru, inaugurating the massive Chancay deep-water port there and being welcomed in Brazil's capital next week for a state visit.
