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.

In what was the last meeting between Chinese President Xi Jinping and U.S. President Joe Biden as Biden prepares to exit the White House in January, Xi warned Biden to “make the wise choice” to ensure the “peaceful coexistence” of the United States and China.

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.
