On November 23, the World Table Tennis Championships were held in the United States. It is worth mentioning that 2021 is the 50th anniversary of the “ping pong diplomacy”, which has been of great significance for the improvement of China-U.S. relations. In the Sixth China-U.S. Young Scholars Forum, which was held in September 22 and co-hosted by 环球时报, The Carter Center, and #iGCU, scholars from both sides also talked about the importance of “ping pong diplomacy” for the improvement of relationships between the two countries.
