Examines the way a Zone of Peace, Freedom and Neutrality (ZOPFAN) concept deals with the special problems of regional neutrality since the neutralization of conflicts in the region (internal neutrality) must be the presupposition of region's neutrality vis-a-vis conflicts between outside powers (external neutrality). Discusses from neutralization to ZOPFAN in terms of the attempts at neutralization, the Malaysian proposal, the ASEAN compromise, and the Kuala Lumpur declaration. Describes ZOPFAN in theory, and ZOPFAN in reality. Includes appendices, covering Declaration on the Promotion of World Peace and Cooperation 1955, the ASEAN Declaration 1967, ZOPFAN 1971, Joint Communique of the Meeting of Foreign Ministers of ASEAN Countries 1971, and Treaty of Amity and Cooperation in Southeast Asia 1976
