On July 20 1940, Yosuke Matsuoka became Minister of Foreign Affairs in the second Konoe Cabinet, and was trying to build a strong partnership with Germany and Italy. On September 9, 1940, he started negotiations for the alliance, and persuaded the Navy during the talks about their obligation to join a war (when any one of the countries enters a war, the other alliance countries have the obligation to participate in the war). At the same time, he held a conference with Germany to request a compromise from them, and the Tripartite Pact was signed on September 27. After that, he attempted to complete the Four-Power Entente including the Soviet Union, and went to visit Germany and the Soviet Union on March 12, 1941.
