Joe Biden met Chinese counterpart Xi Jinping for the final time as president Saturday in Peru as the specter of Donald Trump's return to the White House took center stage at the Asia-Pacific economic summit.

Donald Trump has made a tougher stance toward China central to his pitch on foreign policy, even as Joe Biden and Xi Jinping sought to lower tensions before the next president takes office.

We are the most important alliance – or the most important relationship in the entire world, and how we’re getting along together can impact the rest of the world,” Biden said.
