German–Soviet Credit Agreement (1939), in which the Soviets provided the oil and other important resources that fueled the Nazi war machine, which was used to invade Europe and then ironically also the USSR. This oil was essential to the war effort as nobody else was giving it to the Nazis, and they themselves were agreed that without it they wouldn't stand a chance.
The accompanying Molotov–Ribbentrop Pact, a non-aggression pact between Nazi Germany and the Soviet Union that enabled those two powers to partition Poland between them. Here you can check out the fancy Nazi-Communist military parade celebration of their agreement, where swastikas and red stars stand together.

The Lipetsk fighter-pilot school, secret facility operational until 1933 in Soviet territory, where Germany evaded their ban on operating an air force following the first war. The Soviets approached Germany with the offer, effectively training the predecessors to the Luftwaffe and creating the condtions for them.
The Kama Tank School, and the Tomka gas test site, same story but tank research and chemical weapons development.
