The Helsinki Accords 1975
USA, USSR, France, UK and 31 other countries met in Helsinki Finland.
Agreed to accept European frontiers, respect human rights (particularly USSR), which would make the movement of people across borders easier especially in Europe. The purpose of the Helsinki Accords was to also improve relations between the communist bloc and the West. The document was seen both as a significant step toward reducing Cold
War tensions and as a major diplomatic boost for the Soviet Union
at the time, due to its clauses on the inviolability of national borders and
respect for territorial integrity, which were seen to consolidate the USSR's
territorial gains in Eastern Europe following the Second World War. Considering objections from Canada, Spain, Ireland and other states, the Final Act simply stated that "frontiers" in Europe should be stable, but those borders could be changed by peaceful means.
