This visit, and its cause, was truly historic: until this point, our nation had never had diplomatic relations with the People's Republic of China (P.R.C.). Since the P.R.C's founding on October 1, 1949, the United States had maintained diplomatic ties exclusively with the political remnant of Nationalist China's forces that had been driven from the mainland to the island of Taiwan. This relationship had become deeply embedded in the commercial, media, political, and military establishments of our country. During this time, the P.R.C. was almost invariably referred to in political debates as Red China and Communist, which had a negative connotation similar to the one terrorist has today. To me, Deng Xiaoping's welcome in Washington was an early indication of approval for the decision I had made to shift official diplomatic relations to mainland China.
