In which world capital city did the U.S. and the Soviet Union first hold Strategic Arms Limitation Talks (SALT) in 1969?

Two key agreements between the United States and the Soviet Union emerged from the strategic arms limitation talks (SALT) that occurred in Helsinski, Finland in November 1969. They spanned the first administration of President Richard M. Nixon (1969–1973). The first was an interim executive agreement that froze certain categories of strategic nuclear offensive forces for a five-year period. The second was a treaty of unlimited duration that restricted anti-ballistic missile systems (ABM).

The combined SALT agreements culminated a three-year effort by the Nixon administration to achieve an offensive-defensive linkage that would halt Soviet nuclear modernization efforts and simultaneously restrict the development and deployment of anti-ballistic missile systems by both the U.S. and Soviet Union.

SALT I, as the first two agreements were collectively known, originated in the last years of President Lyndon B. Johnson's administration. The two nations discussed the subject conceptually at the Glassboro summit in 1967. Johnson announced in July 1968 that they had agreed to begin discussions to limit strategic weapons. Due to the political fallout over the Soviet invasion of Czechoslovakia in August 1968, the proposed arms talks were never held.
