Representatives from 21 members representing the Pacific Rim are meeting in Peru for the Asia-Pacific Economic Cooperation forum, the first global summit since U.S.

Still, analysts say he will be overshadowed at APEC by Xi, who arrived on Thursday and proceeded to inaugurate a $US1.3 billion ($A2 billion) mega-port that is perhaps the clearest sign of Latin America's ongoing reorientation in the region.

Biden and Xi are due to hold talks Saturday, in what a US administration official said will probably be the last meeting between the sitting leaders of the world's largest economies before Trump is sworn in in January.
