German–Soviet economic relations (1934–1941)

After the Nazis rose to power in Germany in 1933, relations between Nazi Germany and the Soviet Union began to deteriorate rapidly. Trade between the two sides decreased. Following several years of high tension and rivalry, the two governments began to improve relations in 1939. In August of that year, the countries expanded their economic relationship by entering into a Trade and Credit agreement whereby the Soviet Union sent critical raw materials to Germany in exchange for weapons, military technology and civilian machinery. That deal accompanied the Molotov–Ribbentrop Pact, which contained secret protocols dividing central Europe between them, after which both Nazi forces and Soviet forces invaded territories listed within their "spheres of influence".

The countries later further expanded their economic relationship with a larger commercial agreement in February 1940. Thereafter, Germany received significant amounts of critical raw materials necessary for its future war efforts, such as petroleum, grain, rubber and manganese, while sending weapons, technology and manufacturing machinery to the Soviet Union. After unresolved negotiations regarding a potential Soviet entry into the Axis Pact, the two governments settled several disputes and further expanded their economic dealings with the January 1941 German–Soviet Border and Commercial Agreement.

Economic relations between the two countries were abruptly terminated when Germany invaded the Soviet Union in June 1941, in violation of the Molotov–Ribbentrop Pact.
