North Korea is expected to simultaneously push for economic development and easing military tensions on the Korean Peninsula. However, the construction of social and economic infrastructure in the North's full-fledged economic development process requires astronomical costs. Therefore, it is difficult for the North or the South to carry out large-scale projects such as development of infrastructure and resources by the North alone, so it is necessary to secure various financial resources in line with the North's demand for economic opening and reform. In this sense of problem, this paper reviewed the possibility of using international private capital to supplement national finance as the main source of resources for North Korean development. To that end, this paper examined the cost of infrastructure construction in North Korea. Through analysis of various prior studies, the paper estimated the size of North Korea's development funds, so-called unification costs. It then analyzed the types and scale of international private capital available for North Korean development funds. Finally, by reviewing cases in which international private capital was raised based on the analysis of transition countries such as China and Vietnam, the paper analyzed the types and scale of international private capital that can be procured, and based on this, it derived the elements of policy suggestions for promoting international private capital procurement.
