From 23 - 24 January 2018 UNLIREC and the Ministry of Defense of El Salvador held a workshop on 'the identification of conventional arms and ammunition', in El Salvador, with funding from the ATT Voluntary Trust Fund (VTF). The UNLIREC ATT team lead a discussion on the specific regulations in the Treaty, focusing on the technical characteristics of conventional arms, ammunition and their parts and components. The team also led discussions on the principles governing the different categories of conventional arms mentioned in the ATT, given that they will necessarily form part of the respective National Control List of El Salvador and, in turn, could be the subject of international exchange enshrined in the Treaty. 23 representatives from the Joint General Staff, Customs Authorities, National Civil Police, INTERPOL, the Policy Directorate and the Logistics Directorate of the Ministry of National Defence, as well as the Ministry of Foreign Affairs, participated in the workshop.
