Previously was one single country but was later divided by USA and Russia in 1945 following Japanese surrender.. What are this two contry

Answer 1

The two countries you are referring to are North Korea and South Korea. After Japan's surrender in World War II in 1945, the Korean Peninsula was divided along the 38th parallel into two occupation zones: the northern zone was occupied by the Soviet Union (now Russia), and the southern zone was occupied by the United States. This division eventually led to the establishment of two separate countries in 1948: the Democratic People's Republic of Korea (North Korea) and the Republic of Korea (South Korea).
