The “common technical commissions” demanded by the pact were established by an agreement of 20 December 1940. They should be composed of a general commission in each capital, composed of the host`s foreign minister and ambassadors from the two partner partners. There should be military and economic commissions under the General Commission. On 15 December 1941, the first meeting of the three committees was held in a capital, Berlin, called the Tripartite Pact Conference. It was decided to form a “Permanent Council of Tripartite Powers” but for two months nothing happened. Only the Italians, whom the Japanese were suspicious of, insisted on greater cooperation.  Shortly before the establishment of the tripartite pact, the Soviet Union was informed of its existence and the potential for accession.  Vyacheslav Molotov was therefore sent to Berlin to discuss the pact and the possibility of the accession of the Soviet Union.  The Soviets viewed membership of the tripartite pact as an update of existing agreements with Germany.  During the visit to Berlin, Molotov accepted the principle of the Soviet Union`s accession to the pact if certain details, such as the Soviet annexation of Finland, could be elaborated.  On 25 November, the Soviet government sent Germany a revised version of the pact.
 To demonstrate the benefits of the partnership, the Soviet Union made great economic offers to Germany.  ARTICLE II. Italy, Germany and Japan each commit to suring that none of the parties to this agreement be concluded without a ceasefire or peacefully, either with the United States or with England without a full and reciprocal agreement [of the three signatories to this pact]. Economic relations between the tripartite powers have been marred by difficulties. Japan would not make economic concessions to Germany in 1941, fearing that they would ruin its negotiations with the United States. Negotiations on economic cooperation began in January 1942, but an agreement was not signed until 20 January 1943 in Berlin. Italy was invited to sign a similar agreement simultaneously in Rome for propaganda purposes, but none of Berlin`s complementary protocols applied to Italian-Japanese relations.  To resolve some of the problems, the United States, Germany and the United Kingdom agreed to a conference in Washington in June 1887. After the énigmation of serious disagreements between the parties, the conference was postponed without result.
Fighting by nationals of the three powers with their local allies resulted in a conflict only mitigated by Hurricane Apia of 1889, which destroyed warships at the brink of hostilities. The tripartite pact was, together with the anti-communist pact and the steel pact, one of the many agreements between Germany, Japan, Italy and other countries of the Axis powers that govern their relations.  The German government “had never hidden its belief that international control over Samoa was visionary and inse with little practice… and they have begun a series of diplomatic efforts to eliminate them completely.  In the summer of 1899, German diplomats in Washington found that the U.S. government was satisfied with the acquisition of Tutuila Island with its main property, the existing coal-fired power plant at Pago Pago. With the “partition of Samoa” until then the dominant agreement, the United States did not object to Britain and Germany for “achieving a provisional agreement”.  According to the joint declaration, the parties concerned have already agreed on the following objectives: the tripartite pact, an agreement reached by Germany, Italy and Japan on 27 September 1940, one year after the start of the Second World War.
