The Moscow Summit of 1974 was a summit meeting between President Richard M. Nixon of the United States and General Secretary Leonid Brezhnev of the Communist Party of the Soviet Union. It was held June 28–1 July 1974.  It featured the signing of the Threshold Test Ban Treaty (TTBT). The summit followed the Washington Summit the previous year as well as considerable progress in U.S.-Soviet relations made by Nixon in the previous two years. The visit was the final one of Nixon's presidency as he would give his resignation speech in August of that year.
