 By autumn 1940, after conquering its portion of Poland, the Third Reich shared an extensive border with USSR, with whom it remained neutrally bound by their non-aggression pact and trade agreements.Another consequence of the Molotov-Ribbentrop Pact was the Soviet occupation of Bessarabia and Northern Bukovina, carried out by the Southern Front in June–July 1940 and Soviet occupation of the Baltic states (1940).These conquests also added to the border the Soviet Union shared with Nazi-controlled areas.
