From 29 to 30 November 2017, UNODC's Global Firearms Programme in cooperation with the Government of Panama and funding from the European Union (EU) organised a regional meeting for Member States from Latin America with the scope of enhancing national and international data collection and analysis efforts in order to monitor illicit firearms trafficking flows. The meeting also addressed the development of a basis for the monitoring and achievement of Sustainable Development Goal target 16.4, which aims at reducing arms flows and combating all forms of organized crime. Thirty-six representatives from national arms control agencies in charge of firearms, registries and data collection, as well as investigators, prosecutors and police from fourteen countries (Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, El Salvador, Mexico, Panama, Paraguay, Peru, and Uruguay) attended the meeting. The strengthening of data collection methods forms an integral part of the mandate of UNODC and its Global Firearms Programme. This meeting for Latin American Member States was the second of a series of meetings organized by UNODC as part of its EU-funded project to support global data collection and analysis on firearms trafficking and promote information exchange and cooperation among trafficking routes. The first meeting took place in Addis Ababa in September 2017 and involved Member States from the African region. The regional meeting for Latin American Member States was entirely funded from the European Union (DG Home).
