Beijing is ready to improve ties with Washington, a senior Chinese official said Wednesday, days before a highly anticipated potential meeting between leaders Xi Jinping and Joe Biden in San Francisco.

Recent high-level meetings have sent out “positive signals and raised the expectations of the international community on the improvement of China-US relations,” Vice-President Han Zheng told the Bloomberg New Economy Forum in Singapore.

“We are ready to strengthen the communication and dialogue with the United States at all levels, promote mutually beneficial cooperation, properly manage differences, and jointly address global challenges,” Han said.
