The purpose of this paper is to analyze the strategies for the security and survival of the nation in the context of competition and confrontation between the US and the non - US hegemonic countries, and rapid international relations in East Asia. Northeast Asia in the 21st century is undergoing a period of strategic upheaval. There are still many discussions on the scope and extent of change, and there seem to be more areas where the agreement is not made. However, from a theoretical point of view of international relations, it is becoming necessary to discuss the new stage. This is because the relationship between the United States and China in the Northeast Asia region seems to be narrowing the space for cooperation and gradually increasing competition.
There is still controversy as to whether the bilateral relationship is a full-scale hegemony. However, since major countries in Northeast Asia seem to have begun to have such a perception, we will now see how the countries that have recognized this, beyond competition and competition of regional hegemony of US and China, will show their behavior in the future. There is a need to predict whether or not it will affect.
It is a vital task for Korea to prepare a countermeasure strategy for the existence, prosperity and unification of the nation by each type of new international order. Korea has a bitter experience of being a Japanese colonialist by misunderstanding and judging the words, the international situation surrounding the Korean Peninsula and Northeast Asia. At that time, the ruling class in Korea did not properly perceive the imperialist rivalries and conflicts of the Yakugaku-kun held by the surrounding powers, and finally failed to search the future destination without reading the coordinates accurately. The result was the disgraceful loss of national rights and the terrible suffering of the people.
