In Asia, China and North Korea embark on diplomatic coercion by force. North Korea has attempted to achieve its political goals through nuclear and missile development and threats to the international community. China tried to control the South China Sea through the direct use of military power in the South China Sea. China has used economic sanctions against the world to achieve its political objectives. The international community, however, has succumbed to the coercion diplomacy of these two countries, but there are some countries that subvert China. In particular, China has shown a subservient attitude to the US`s coercive diplomacy, which overwhelms China`s power. This study analyzed the arrogance and humiliation of diplomacy in Chinese power and analyzed US regulations on North Korea.
