What was the significance of Nixon's trip to china?

U.S. President Richard Nixon's 1972 visit to the People's Republic of China was an important step in formally normalizing relations between the United States and the People's Republic of China (PRC). It marked the first time a U.S. president had visited the PRC, which at that time considered the U.S. one of its staunchest foes, and the voyage ended 25 years of separation between the two sides. Prior to even being elected president, Richard Nixon had sought better relations with the PRC, with which the U.S. did not maintain diplomatic relations as it recognized the Republic of China on Taiwan as the government of China. Early in his first term Nixon and National Security Adviser Henry Kissinger began sending subtle overtures hinting at warmer relations to the PRC government. After a series of these overtures by both countries, Kissinger flew on secret diplomatic missions to Beijing and in July 1971, the President announced that he would visit the PRC the following year.
