The two differences between North and South Korea are as follows: their government and their economy. North and South Korea used to be one country, known as Korea, back in the early days. After World War II ended and the Japanese forces surrendered, Russia and the United States decided to temporarily occupy the North and South respectively until a free and independent Korean government is formed. However, political disagreements between two opposing countries delayed the formation of a Korean government.
With North Korea adopting communism wherein all means of production are owned by the community and a country is ruled by one single political party and South Korea adapting capitalism and democracy. In terms of their economy, South Korea has demonstrated economic growth and global integration in hopes of becoming a high-tech industrialized economy while North Korea faces economic problems.
