The UN Regional Centre for Peace and Disarmament in Africa (UNREC), in collaboration with the Economic Community of West African States (ECOWAS), organised a workshop for ECOWAS Member States on synergies and complementarities between the ATT, the ECOWAS Convention on Small Arms and Light Weapons (SALW), the United Nations Programme of Action (UNPoA) and other related instruments. Discussions centered on the identification of practical measures that allow harmonized implementation of the different arms control instruments regulating the international trade in conventional arms including a national arms transfer control systems, record-keeping and reporting requirements.
