China and Japan are one of the leading countries in terms of economic development in the Asia-Pacific region (APR). The stability of the region directly depends on their relationship, and this trend was observed in the second half of the 20th century. Relations between the countries in the post-war period gradually developed, and in the 1970’s the most favorable stage in the dialogue between the two states took place. The purpose of this study is to identify the main areas of cooperation between Beijing and Tokyo that contributed to the improvement of relations between the countries in the 1970’s. However, while discussing this topic, it is also necessary to pay attention to the difficulties that have grown with each decade since the end of the second Sino-Japanese War. Different political systems, American influence, the problem of Taiwan, territorial disputes, the presence and testing of nuclear weapons – all of these influenced the dialogue between Beijing and Tokyo, but trade and economic cooperation expanded at the same time: trade relations developed, investments were actively poured in, countries united for the implementation of joint projects. The number of various cultural contacts also increased. The scientific novelty of this work is determined by the attempt to provide data on the development of Sino-Japanese dialogue in the post-war period, when the prerequisites for the further favorable development of bilateral contacts were formed, give information about the growth of Sino-Japanese relations in the 1970’s and problems that appeared in the third decade of the 20th century between the two states. As a result of the study, it was revealed that, against the backdrop of trade and economic cooperation, the emerging problems still receded into the background, which can be perceived as a characteristic feature of Sino-Japanese relations, which was formed in the 1970’s and remains relevant until now.
