The Kaesong Industrial Complex (KIC) is a symbol of inter-Korean economic cooperation. Although there have been many political challenges, the complex is still expected to reduce security concerns in the Korean peninsula by providing opportunities for North Korea to open doors to international society. In the field of law, the two Korean governments recognize the uniqueness of the KIC and have tried to establish legal tools for the complex. The complex is subject to certain inter-Korean agreements as well as laws and regulations established by the South and the North. The Korean governments also provide many types of support under inter-Korean agreements and national laws. Almost every South Korean FTA has preferential provisions to recognize KIC products as originating from South Korea, considering the special and unique relationship between the two Koreas. The laws for the KIC are open to change based on internal or external influences. To keep the special project running, however, laws need to be in line with principles to avoid political interferences. Better legal solutions can be found to improve the provisions of inter-Korean, domestic, and FTA laws with new industrial policies.
