The Asia-Pacific Leadership Network for Nuclear Non-Proliferation and Disarmament (APLN) has over one hundred members from eighteen countries across Asia and the Pacific, consisting of former political, diplomatic and military leaders, senior government officials, and scholars and opinion leaders. APLN aims to inform and energize public opinion, especially high-level policymakers, to take seriously the very real threats posed by nuclear weapons, and to do everything possible to achieve a world in which they are contained, diminished and eventually eliminated.
