The Power Balance Factor and the Relative Stability of Northeast Asia in the 1920s

As an important geographical unit, Northeast Asia has long been plagued by frequent hot spots. In modern times, the overall situation in Northeast Asia has been turbulent, with frequent wars and unrest. However, in the 1920s, there was a period of relative stability in Northeast Asia. This study reviews the academic context and research gaps, introduces the theory of power balance, explains the formation of the Vienna system and the principle of power balance, and introduces the power balance diplomatic practices of countries such as Britain, France, and Russia. After reviewing the situation in China in the early 20th century, the study introduces the factor of power balance into the analysis of the Northeast Asian landscape in the 1920s. It examines various areas, including the strength, strategies, and mutual constraints of major regional powers such as Japan and Russia; the relative constraints of international treaties and systems; the growth in strength and foreign policies of local powers in Northeast China; and the policies and interventions of Western powers outside the region. Research suggests that a balance of power emerged in Northeast Asia in the 1920s, with relative stability resulting from the combined effects of various traditional and unique power balance factors.
