The primary source of political conflict between China, Japan, and South Korea is "land claims in the South China Sea."

While trade barriers, nuclear weapons development, and economic sanctions can also be points of contention involving these countries, the territorial disputes in the South China Sea specifically engage these nations in complex geopolitical tensions, particularly as they relate to China's assertive claims over this crucial maritime region, which overlaps claims from several Southeast Asian nations.
