US President Richard Nixon Visits China

From February 21 to 28, 1972, President Richard Nixon visited China, the first leader ever to visit from a country that had not yet established diplomatic relations with China. Mao Zedong held historic and significant talks with Nixon. On February 27, China and the US issued their first joint Communique in which both nations pledged to work toward full normalization of diplomatic relations. This was the Joint Communique between the People's Republic of China and the United States of America – also known as the "Shanghai Communique." It represented the end of an old era and the beginning of a new one in China-US relations.
