Jumping the hurdles

Disarmament and international security is an issue that concerns all state in the world, yet not all states have traditionally been active in moving this agenda forward. In this background paper we take a closer look at the numbers behind the assumption, with a particular focus on recent multilateral arms control and disarmament meetings. The data show, not surprisingly, that developing states tend to be underrepresented on these arenas, but also that certain measures seem to be effective in terms of increasing their participation. We analyse and discuss some of the root causes of this ‘development gap’, and end with a set of policy recommendations that stakeholders may want to consider in their efforts to improve the inclusiveness of multilateral disarmament processes.
