What is the Asian nation divided into two nations?

The Asian nation that was divided into two independent countries is Korea, which is located on the Korean peninsula in East Asia. Korea used to be a unified country, but became divided after World War II, when the Soviet Union occupied the northern part and the United States occupied the southern part. This political division led to the establishment of two separate Korean states: North Korea and South Korea. These countries have remained divided to this day, with different political systems and ideologies.
