The Government of Samoa and the United Nations Regional Centre for Peace and Disarmament in Asia and the Pacific (UNRCPD) jointly organized a workshop on building national and regional capacity for the implementation of the Arms Trade Treaty (ATT) in the Pacific, in Apia Samoa, from 13 to 15 September 2016. The workshop, which was made possible with the financial support from the Governments of Australia and New Zealand, brought together approximately 25 participants from Pacific Island States to meet with international arms control experts from government, civil society and academia. This event was one of the first of its kind to be hosted on location in a Pacific Island State. The three-day workshop covered issues related to the implementation of the ATT, including sessions on the outcomes of the second Conference of States Parties to the ATT; the steps, benefits, and challenges of joining the ATT; the reporting requirements of the Treaty, options for future assistance; the development of national control systems; and the broader relevance of the ATT for the Pacific Region.
