North Korea is located on the Korean Peninsula in Eastern Asia, bordering South Korea, China, and Russia. The country split into North and South Korea after World War II, and tensions escalated when North Korea invaded South Korea in 1950, starting the Korean War. North Korea is now a communist state led by Kim Jong-un as dictator, with a struggling economy that relies on agriculture and has faced frequent floods and food shortages. The government maintains strict control over movement and religion within the closed country.
