Following World War II, Korea was split, with the northern half coming under Communist domination and the southern portion becoming Western-oriented. KIM Chong-il has ruled North Korea since his father and the country's founder, president KIM Il-song, died in 1994. After decades of mismanagement, the North relies heavily on international food aid to feed its population while continuing to expend resources to maintain an army of about 1 million. North Korea's long-range missile development and research into nuclear, chemical, and biological weapons and massive conventional armed forces are of major concern to the international community. In December 2002, North Korea repudiated a 1994 agreement that shut down its nuclear reactors and expelled UN monitors, further raising fears it would produce nuclear weapons.

North Korea and South Korea dispute the name of the sea bordered by China, Japan, North Korea, Russia and South Korea. While Japan, as the map depicts, calls it the Sea of Japan, South Korea and North Korea maintain that its name is the East Sea and East Sea of Korea, respectively.
