China and North Korea have been close allies for a very long time. China is the only country who will trade with North Korea. China supported North Korea in the Korean war and have kept close ties since. However, in the past few years, China has become more and more worried about North Korea and their government. China is preparing for the collapse of the North Korean government. The Chinese have drawn up extensive contingency plans that include the detainment of important North Korean leaders and the creation of refugee camps along the border. It appears that North Korea may have lost its one and only ally.
