This four-day workshop organized by Nonviolence International Southeast Asia and the Pacific Small Arms Action Group (PSAAG) – both members of the Control Arms network – brought together participants from eight South-East Asian and Pacific Island states for a training workshop on the ATT and national implementation mechanisms. Discussions focused on exploring the roles and responsibilities of various government departments (e.g. customs agencies), questions of legal competence, and exploring the relationship of the ATT with other relevant agreements like the UNPoA, and the UN Convention Against Organised Crime. The workshop also opened avenues for communications and encouraged sharing of information among the participating countries, to further their capacities in implementing the ATT. It particularly focussed on how to conduct an effective risk assessment, develop effective transit and trans-shipment systems for transit-hub countries, and on how to establish effective national control systems and prepare annual reports.
