戦略兵器制限交渉
In the late 1960s and early 1970s, Soviet-American relations began to improve again. On May 26, 1972, President Richard Nixon, Soviet General Secretary Leonid Brezhnev and Premier Alexei Kosygin used Spaso House as the venue to announce their agreement on the first round of Strategic Arms Limitation Talks (SALT 1) and on an Anti-Ballistic Missile Treaty. The treaties were signed shortly afterwards at the Kremlin.
