German–Soviet economic relations (1934–1941) in the context of German–Soviet Axis talks

The Molotov–Ribbentrop Pact, officially the Treaty of Non-Aggression between Germany and the Union of Soviet Socialist Republics, and also known as the Hitler–Stalin Pact, the Berlin–Moscow Pact and the Nazi–Soviet Pact, was a non-aggression pact between Nazi Germany and the Soviet Union, with a secret protocol establishing Soviet and German spheres of influence across Eastern Europe. The pact was signed in Moscow on 24 August 1939 (backdated 23 August 1939) by Soviet Foreign Minister Vyacheslav Molotov and German Foreign Minister Joachim von Ribbentrop.

Tripartite discussions between the Soviet Union, the United Kingdom and France had broken down after the Soviet Union was excluded from the Munich Agreement in September 1938. Joseph Stalin, the General Secretary of the Communist Party of the Soviet Union, had indicated that the USSR was willing to support Czechoslovakia militarily if France did so as well. Subsequently, rapprochement between Soviet Union and Nazi Germany began in early 1939. Later that year the Soviet-German pact was agreed, committing both sides to neither aid nor ally itself with an enemy of the other for the following 10 years. Under the Secret Additional Protocol of 23 August 1939, Germany and the Soviet Union agreed to partition Poland; Latvia, Estonia, Finland and Bessarabia were allotted to the Soviet sphere, while Lithuania – apart from the Vilnius region, whose "interests" were recognized – lay in the German sphere (Lithuania – including the Vilnius region, but excluding a strip of land – was only transferred to the Soviet sphere by the 28 September 1939 Boundary and Friendship Treaty). In the west, rumored existence of the Secret Protocol was proven only when it was made public during the Nuremberg trials.

The German–Soviet Credit Agreement (also referred to as the German–Soviet Trade and Credit Agreement) was an economic arrangement between Nazi Germany and the Soviet Union whereby the latter received an acceptance credit of 200 million ℛ︁ℳ︁ over seven years with an effective interest rate of 4.5 percent. The credit line was to be used during the next two years for purchase of capital goods (factory equipment, installations, machinery and machine tools, ships, vehicles, and other means of transport) in Germany and was to be paid off by means of Soviet material shipment from 1946 onwards. The economic agreement was the first step toward improvement in relations between the Soviet Union and Germany.

On 11 May 1939, the day after the Credit Agreement, the Soviet Union went to war against Japan in a successful four-week military campaign in the Far East. The Nazi-Soviet Pact was signed four days after the Credit Agreement. The 1939 German–Soviet Commercial Agreement renewed declined German–Soviet economic relations and was adjusted and expanded with the larger German–Soviet Commercial Agreement in February 1940 and January 1941 German–Soviet Border and Commercial Agreement. German shipments to the Soviets became tardy and failed to provide all that was promised the closer the date of Barbarossa came. The Soviets fulfilled their obligations to the letter right up until the invasion, wanting to avoid provoking Germany. All these agreements were terminated when Germany invaded the Soviet Union in June 1941, in violation of the treaties between the two countries. Soviet trade with Germany in the pre-invasion period ended up providing the Germans with many of the resources they needed for their invasion of the Soviet Union.

The German–Soviet Border and Commercial Agreement, signed on January 10, 1941, was a broad agreement which settled border disputes, and continued raw materials and war machine trade between the Soviet Union and Nazi Germany. The agreement continued the countries' relationship that started in 1939 with the Molotov–Ribbentrop Pact, which contained secret protocols that divided Eastern Europe between the Soviet Union and Germany. The relationship had continued with the subsequent invasions by Germany and the Soviet Union of that territory. The agreement contained additional secret protocols, settling a dispute regarding land in Lithuania, which had been split between both countries. The agreement continued the German–Soviet economic relations that had been expanded by the 1939 German–Soviet Commercial Agreement and the more comprehensive 1940 German–Soviet Commercial Agreement.

The agreement proved to be short-lived. Just six months after it was signed, Germany invaded the Soviet Union, which ended economic relations between them. The raw materials imported by Germany from the Soviet Union between 1939 and 1941 played a major role in supporting the German war effort against the Soviet Union after 1941.
