After the death of Kim Il-sung in 1994, his son, Kim Jong-il, succeeded him in a dynastic manner. Following Kim Jong-il's death in 2011, Kim Jong-un, one of Kim Jong-il's younger sons, took over the country's leadership. According to the Juche ideology, the country can only rely on itself, but it maintains close relations with other socialist states, such as Vietnam, Laos, Myanmar, and China. Due to the collapse of the Soviet Union and famines in the 1990s, Kim Jong-il introduced economic reforms in 1995, focusing on the military and supporting it.
