Even though ping pong was invented in the 1880s by the English, its association with Chinese athletics is undeniable. In the 1920s, Mao Tse-tung instituted it as a recreational activity for the People’s Liberation Army, which quickly resulted in it becoming China’s most popular sport. The game played a crucial role in the thawing of relations between China and the U.S. In 1971, a U.S. ping pong player, Glenn Cowan, accidentally boarded a Chinese team bus at the World Table Tennis Championships in Nagoya, Japan. Cowan was greeted by Zhuang Zedong of the Chinese team and the two had a conversation via translator. After learning of this exchange, Chairman Mao invited the U.S. team to tour China. President Nixon approved the trip, which ended more than a 20 year period of diplomatic silence between the two nations. In February of 1972, President Nixon visited China and met with Chairman Mao and began normalizing U.S.-China relations. In April of 1972, a Chinese delegation of ping pong players ended up touring America for two weeks; this exchange become known as “ping pong diplomacy.” On April 28, 1972, the Chinese team played an exhibition game at Stanford University’s Maples Pavilion.
