Which is a source of political conflict between China, Japan and South Korea today

One major source of political conflict between China, Japan, and South Korea today is historical tensions and disputes over wartime atrocities and perceived infringements on sovereignty. These countries have a long history of conflict and animosity, with unresolved issues such as Japan's wartime aggression and colonization of Korea and China causing ongoing tensions and disputes. For example, Japan's controversial visit to the Yasukuni Shrine, which honors war criminals from World War II, has sparked outrage in both China and South Korea, leading to diplomatic tensions. Additionally, disputes over territorial claims in the East China Sea and the South China Sea have further strained relations between these countries. Economic competition and regional power dynamics also play a role in the political conflicts between China, Japan, and South Korea.
