The subject of the study is the internal logic of the Soviet negotiation strategy in concluding the fishing convention with Japan from 1922 to 1928 and the transformation of the Soviet side's demands during the negotiations. The object of analysis is the diplomatic and economic mechanisms of Soviet-Japanese interaction, including the use of the fishing issue as a tool for pressure, where economic concessions were linked to political demands, such as the evacuation of Japanese troops from Northern Sakhalin and Japan's actions in Manchuria. The initial demands are examined – reserving up to 35% of fishing areas for state enterprises and extending the concession regime to canning factories – and their subsequent softening. Special attention is given to the convention of January 23, 1928, which established mechanisms for sovereign control, as well as the connection of the negotiation process with internal decisions and the outcomes of implementing the agreement in the late 1920s and early 1930s. The methodological basis of the study consists of the principle of historicism, the comparative-historical method, as well as document analysis and reconstruction of the negotiation process. The scientific novelty of the research lies in the reconstruction of the course of Soviet-Japanese negotiations on the fishing convention from 1922 to 1928 in historical and chronological order, which made it possible to reveal the logic of changes in the Soviet side's negotiation strategy. The main conclusions are the establishment of the regularity of the sequential softening of initial demands – including reserving up to 35% of fishing areas for state enterprises and extending the concession regime to all canning factories – under the influence of the threat of disrupting the fishing season and the tactics of Japanese diplomacy. It is shown that the convention of January 23, 1928, established new mechanisms for sovereign control that were absent in the 1907 agreement, including regulation of labor relations, a system of deductions from canned production, and the provision of 20% of fishing areas to state enterprises without auctions. It has been revealed for the first time that a secret resolution of the Central Executive Committee and the Council of People's Commissars was adopted on September 23, 1927, creating an internal legal framework for the industry. It was established that as a result of the 1929 auctions, the share of Soviet sections increased from 14% to 36%, and in 1934, the production of canned goods reached 55.4%, exceeding the Japanese production.
