After the Cold War, the Yalta system did not completely collapse, but moved the Iron Curtain from Europe to East Asia, resulting in a camp confrontation situation similar to the Cold War pattern in East Asia and the Pacific. All countries in East Asia maintain high-density armaments, and the regional pattern is in a state of tension, so the term "East Asian strange house" has emerged.

Moreover, the strength of many countries in this region far exceeds the world average. In terms of economic strength, the top three countries in GDP: the United States, China and Japan all have influence here; In terms of military strength, the United States, China, Russia and other military powers have also gathered here, and the whole of East Asia is a stage for great powers to compete.

The fundamental reason for the emergence of strange houses in East Asia is that East Asia and the Pacific region has become the forefront of conflicts between different interest groups. Western interests represented by the United States and regional interests represented by China and Russia meet in East Asia. China, Russia, North Korea and the United States, Japan and South Korea have become two camps divided according to geographical interests, political structure and ideology. The two sides are at loggerheads in East Asia, and the smell of gunpowder is getting stronger and stronger.
