Member-states of the Association of Southeast Asian Nations (ASEAN) support the norms of nuclear disarmament and nuclear security through diplomatic efforts at the global level and regional efforts to promote nuclear safety and security. This is demonstrated in how ASEAN helped push for negotiation of the Treaty on the Prohibition of Nuclear Weapons (TPNW) and its eventual passage, as well as ongoing efforts to promote regional cooperation in advancing nuclear security and nuclear safety. Regional frameworks and mechanisms like the ASEAN Network of Regulatory Bodies on Atomic Energy (ASEANTOM), the ASEAN Regional Forum, and the East Asia Summit provide the platforms for ASEAN to advance its diplomacy in promoting the norms of nuclear governance.

This article examines the prospects for the realization of the agreement signed at the 2007 inter-Korean summit to transform the conflict-susceptible Northern Limit Line (NLL) in the West Sea into a border area where South and North Korea jointly promote peace and prosperity. To realize this agreement the two Koreas must integrate new ideas and plans by viewing the NLL as a space of common benefit rather than a line of military confrontation. The establishment of the West Sea Special Zone for Peace and Cooperation focuses on security and economic issues. Implementation of the agreement requires particular attention to development of a comprehensive plan, including promotion of ecological, environmental, historical, and cultural assets, as well as inter-Korean fishery cooperation.
