President Joe Biden and Chinese President Xi Jinping have agreed to meet on the sidelines of next month’s Asia-Pacific Economic Cooperation summit in San Francisco, according to a U.S. official familiar with the planning.

The two sides worked out an agreement in principle to hold a meeting during the summit as Chinese Foreign Minister Wang Yi met Friday with Secretary of State Antony Blinken and White House national security adviser Jake Sullivan, according to the official, who was not authorized to comment and spoke on the condition of anonymity.

The official added that two sides have still not worked out details on the exact day of the meeting, venue and other logistics.
