It has been reported that passenger transport and logistics between regions in North Korea are very difficult due to deterioration and imperfect maintenance of transport infrastructure and limited investment in the facilities for several decades. If South Korea and North Korea are unified, massive investment in the development of transport infrastructure is inevitable. This investment would mainly be supported by South Korea as well as through cooperation with Multilateral Development Banks such as the World Bank Group (WBG), Asian Development Bank (ADB), and Asian Infrastructure Investment Bank (AIIB). In addition, special and efficient plans for transporting people and goods need to be established in case of reunification considering the current transport environment in North Korea. Thus, well-prepared strategies should be in place for short, mid, and long-term perspectives.
