This workshop was organized by UNRCPD, in cooperation with the Government of Laos, with funding provided by UNSCAR. It sought to increase capacities of states in South-East Asia to effectively utilize the PoA reporting mechanism on efforts to prevent and combat illicit trade in SALW. The workshop provided practical advice and skills on collecting national data, as well as preparing and submitting national reports online. UNRCPD organized and conducted two practical exercises aimed at building capacity of States representatives in planning national measures to effectively control SALW and providing practical skills in preparing reports to the PoA. It also sought to develop increased understanding of how PoA reporting can contribute to and support national efforts toward meeting Sustainable Development Goal 16.4. In addition, it provided an opportunity for the participants to discuss synergies between the PoA reporting mechanisms, the Arms Trade Treaty (ATT) and possible elements of National Action Plans.
