It is clear that the NSP started off with the right messages and many Southeast Asian countries have been receptive to the initiatives. Despite the pandemic bringing a lot more challenges in implementing the policy initiatives, the NSP Plus has envisioned an innovation-oriented cooperation by transforming the traditional face-to-face operations to electronic and digitalized management. Public health cooperation is understandably the immediate focus, but such cooperation should be also seen as long-term fulfilment of the cooperation on the People pillar in the NSP. Infrastructure connectivity and South Korea’s cooperation in the building of an evolving East Asian regional architecture respectively enhance the Prosperity and Peace pillars. With patience, dedication, and commitment, the NSP Plus will be a long-lasting foreign policy legacy of Moon that brings benefits to Korea, ASEAN, and regional stability.
