yes / Small arms and light weapons can enter the illicit market at many stages in their lifecycle. From manufacture, to sale/export, to import, and then to final end use, States must establish and enforce stringent and comprehensive licensing and monitoring systems to ensure that small arms and light weapons (SALW) remain under legal control. The UN Conference on the Illicit Trade in Small Arms and Light Weapons in All Its Aspects and ensuing follow-up process provide States with important opportunities to analyse and compare how existing systems governing the manufacture and trade in SALW are working. They further provide the context in which best practice can be agreed and implemented internationally, and for the discussion of how future trends and developments in SALW manufacture and transfer can be more effectively brought within State control. To this end, this briefing paper covers two separate but closely related issues. The first section of the report will analyse existing State and regional controls on SALW manufacture and examine how international measures, including the UN Conference, can reinforce such controls. In this regard, the growth of licensed production and co-production agreements is highlighted, together with implications for the development of adequate regulations. The second section examines those systems that are currently in place for the authorisation of SALW transfers and for the certification and monitoring of their ultimate end-use. Recommendations for best practice and implications for the UN Conference process are also discussed.
