Since the BRI was launched, China has been actively promoting cross-border economic cooperation with neighbors in border areas, providing some implications for Korea's future development in the era of peace and prosperity in Northeast Asia. First, in order to prepare for a new era of peace and prosperity between North and South Korea, a new understanding of border security and border areas is needed. It is necessary to change perceptions regarding the border regions, recognizing them as more than segmented boundaries at the forefront of military security, and rather as platforms of cross-border economic cooperation and a testbed for economic integration. Second, it is necessary to find ways to leverage the unified economic special zone as a test bed for regional integration in the border areas with Korea just as China's CRECZs. We must find a way to emulate China's CBECZ model to utilize the cooperation platform and regional integration testbed between South and North Korea, or the Korean Peninsula and China. Finally, we need to strengthen cross-border infrastructure linkages to lay the foundation for regional integration. The South Korean government needs to actively promote the establishment of infrastructure for the regional integration of South and North Korea by implementing the plans suggested within the New Economic Map of the Korean Peninsula for cross-border infrastructure projects in areas such as transportation, communication, energy, and logistics.
