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

Question

trade barriers, nuclear weapons development, land claims in the South China Sea, economic sanctions

Answer 1

The source of political conflict between China, Japan, and South Korea today primarily revolves around land claims in the South China Sea. While trade barriers, nuclear weapons development, and economic sanctions can be points of tension in the broader Asia-Pacific region, the specific territorial disputes, particularly in relation to maritime boundaries and islands, are a significant issue affecting relations among these countries. China has ongoing territorial disputes in the South China Sea, which are contested by several nations in the region, including Japan and South Korea, leading to increased tensions and political conflict.
