Purpose: The United Nations recently announced A4P+, a priority for the implementation of A4P following A4P to emphasize the qualitative improvement of peacekeeping operations and the sharing of responsibilities among related actors. In this paper, I will consider the A4P+ priorities to be implemented for UN peacekeeping operations between 2021-2023 and draw implications for the Korean military deployment policy in peacekeeping. Method: To this end, Literature analysis centered on official documents published by the United Nations relat-ed to A4P and A4P+, was conducted, and military-related data were referenced among various data on the United Nations web page. Results: A4P and A4P+ presented areas and tasks to be implemented in peacekeeping operations by the UN, member states, regional organizations, and host governments related to the deployment of UN personnel. Up-holding A4P and A4P+ are WPS(Women, Peace, and Security) and data-driven and advanced technologies. All stakeholders in Peacekeeping must do their commitments in eight areas of A4P and prepare for the materialization of A4P through A4P+ priorities based on the two. Member states providing military and police are responsi-ble for providing their competent peacekeepers to field missions for their safety and security and mandate implementation. Peacekeeping operations emphasize high-tech and information collection systems for effectiveness and efficiency of peacekeeping, TCC/PCC should read and reflect the changes required from the UN into their deployment policy. Conclusion: Korea should do its commitment pledged to the UN to contribute to successful peacekeeping oper-ations. First, Korea shall contemplate its deployment policy, focusing on how and what it can implement A4P+ within a limited period. Second, Korea needs to re-consider the current participation of military and equipment. Qualitative expansion in Korea’s participation rather than quantitative one should be prioritized first.
