Tripartite Pact Saburō Kurusu Imperial Japan Bulgaria Axis powers Molotov foreign minister invasion of the Soviet Union Hungary Japan de Berlin
On 27 September 1940, the Tripartite Pact was signed in Berlin by Saburō Kurusu of Imperial Japan, Hitler, and Italian foreign minister Ciano, and later expanded to include Hungary, Romania, and Bulgaria, thus yielding the Axis powers. Hitler's attempt to integrate the Soviet Union into the anti-British bloc failed after inconclusive talks between Hitler and Molotov in Berlin in November, and he ordered preparations for the invasion of the Soviet Union.
