Myanmar is a multi-ethnic country. Since its independence from British colonial rule in 1948, it has been troubled by various conflicts between ethnic minorities and the central government. The issue in northern Myanmar is the result of the interaction of many factors in past history and reality. . Now, with Japan's intervention, the situation in Myanmar's civil war has changed again. In order to check and balance China and obtain Myanmar's rich mineral resources, Japan has intervened in Myanmar's economy and military. On the one hand, it incited military action and in order to stabilize its political foundation in the chaos, it gave small favors to the people of Myanmar in the form of economic support. On the other hand, it joined other Western countries in condemning Myanmar's military action.
