The Strategic Arms Limitation Talks (SALT I) agreement in 1972 brought about

SALT I was an agreement between the United States and the Soviet Union to limit strategic nuclear weapons. Its interim agreement placed limits on the number of Soviet (and U.S.) missile launchers, including those for intercontinental and submarine-launched ballistic missiles. Therefore, the choice about regulating Soviet production of missiles carrying nuclear weapons is the best answer; SALT I did not regulate China’s weapons or recognize China.
