Since Japanese Prime Minister Shinzo Abe administration came into power, Japan’s relationship with China and Korea has been in severe trouble. At present, the main issue is that the public opinions and politicians should help build steps for compromise, which is the only choice to achieve the “win‐win” goal. Facing the future, the starting point for reconciliation in East Asia should be focused on how to get through the gap between concepts. From China’s perspective, as long as the nightmare of the “Greater East Asia Co‐Prosperity Sphere” is not removed, the shadow of the “China Threat Theory” lingers, and if China can not take on more responsibility in the international community, it is impossible to find a reasonable internal logic for regionalism, the East Asian Community, and the vision of a harmonious world. The analysis and resolution of the historical nightmare of the “Greater East Asia Co‐Prosperity Sphere” might help to warn those bigots in Japan who believe that “there is a reasonable nature in the past colonial rule and war”. Dealing with “China Threat Theory” and “China Responsibility Theory” correctly is an opportunity for China to defend itself as well as to demonstrate its new image to the whole world.
