The purpose of this study is to predict the changes in the international order that the COVID-19 pandemic will bring, and draw implications and implications based on the theory of emerging security. The emerging security theory, which contrasts with traditional security through the COVID-19 pandemic, will need to be redefined to match the post corona era. The international order in the post corona era due to the COVID-19 pandemic will have a deglobalization and deepening of US-China strategic competition, competition for system superiority, self-prosperity, risk of flooding of nationalism, and a desire for international governance. Through the COVID-19 Pandemic, it was an opportunity to re-recognize emerging security threats, and through the response of a new infectious disease called COVID-19 and a new security threat, Korea is faced with new threats and opportunities. Korea should actively and preemptively accept the change of the new international order in preparation for the post corona era and use it as an opportunity to turn the crisis into an opportunity.
