President Richard Nixon implemented a new approach to foreign policy during his presidency called détente. He sought to improve relations with both China and the Soviet Union based on pragmatic national interests rather than ideology. Nixon and his adviser Henry Kissinger pursued diplomatic relations with China, resulting in Nixon's 1972 visit to China. Nixon also met with Soviet leader Brezhnev, signing arms agreements and promoting cooperation to reduce Cold War tensions. These breakthroughs shifted relations away from the old policy of suspicion and distrust toward a thawing of tensions between the superpowers.
