The US foreign policy during the presidency of Richard Nixon (1969–1974) focused on reducing the dangers of the Cold War among the Soviet Union and China. President Richard Nixon's policy sought on détente with both nations, which were hostile to the U.S. and to each other. He moved away from the traditional American policy of containment of Communism, hoping each side would seek American favor. Nixon's 1972 visit to China ushered in a new era of U.S.-China relations and effectively removed China as a Cold War foe. The Nixon administration signed the Anti-Ballistic Missile Treaty with the Soviet Union and organized a conference that led to the signing of the Helsinki Accords after Nixon left office.
