From June 25-27, 2018, the International Institute for Justice and the Rule of Law (IIJ) hosted the Strategic Trade Control and Counterproliferation: Investigation and Prosecution workshop in Valletta, Malta. IIJ welcomed twenty-eight investigators and nine prosecutors from seven Balkan nations, in addition to Poland, Romania, Slovenia, and Bulgaria. The three-day interactive workshop brings together a diverse team of experts to share their insights on recent trends and challenges of national and transnational proliferation and to moderate collaborative exchanges about best counterproliferation practices and technical expertise among criminal justice practitioners. Workshop sessions address topics relevant to every stage of the strategic trade control system, from international and interagency communication and proliferation awareness for policymakers, to sharing information about current legal/regulatory models and licensing practices. Each session also includes practical exercises involving commodity identification training and detection. The workshop aims to facilitate the harmonization of national export control systems with international standards, thus producing better cross-border understanding of non-proliferation related programs and initiatives.
