North Korea usually uses the nuclear threat to assert its international position and hold a bargaining chip in discussions with other big powers, especially with the United States. Furthermore, North Korea increases the tension in north-east Asia to show the strength of its nuclear weapons and bring the pressures to South Korea, Japan, and America. In North Korea, military objectives are prior to others, which creates serious problems at home, resulting in famines and economic problems. Given this dilemma, North Korea is devoted to economic development strategies. Since the demise of Kim Jong-il, North Korea has begun to use its geographical position, plenteous natural resources and strong neighbors to develop its economy and strengthen its international position in north-east Asia. By means of geo-political-economic strategies, North Korea can build a stable strategy base, solve its economic problems and break the old strategy of a nuclear threat to get more space abroad vis-à-vis China, the USA, South Korea, and Japan.
