The legacy of Japan's war of aggression against China is not only an internal problem of how Japan understands the history of the war of aggression and adopts corresponding principles, policies and strategies; Whether Japan obeys international judgments, fulfills international treaties and abides by the principles of bilateral political documents between China and Japan is also a question of national integrity; It is also related to the feelings and dignity of the people of the victimized countries in Asia, including China, the political basis for the development of Sino-Japanese relations, and the stable and peaceful international relations in East Asia. As far as China is concerned, the legacy of Japan's war of aggression against China is a realistic issue of how Japan correctly understands the history of its war of aggression against China, and it is also a major issue involving the political foundation of Sino-Japanese relations.
