China’s foreign minister considers that the road to an expected meeting between President Xi Jinping and US President Joe Biden would not be “smooth-sailing” and that both sides must work together to achieve results, the foreign ministry said on Sunday.

Wang Yi met with Biden, as well as secretary of state Antony Blinken and national security advisor Jake Sullivan, during a three-day visit to Washington. Both sides agreed to work toward a bilateral meeting at the upcoming Asia-Pacific Economic Cooperation forum summit in San Francisco in November.
