He visited the People's Republic of China in 1972 for the eventual start of diplomatic relations between the two nations and the initiation of the detention of the Anti-Ballistic Missiles with the signing of a treaty with the Soviet Union that same year. His administration generally transferred the power of Washington D.C. to the states. It imposed salary and price control for ninety days, suspending the gold standard and entering the fiduciary money.
