This book provides a detailed analysis on the history and development of the Committee on the Peaceful Uses of Outer Space (UNCOPUOS) and the Conference on Disarmament (CD) and the coordination and cooperation between these two fora. Furthermore, it discusses the future challenges that these fora will have to deal with and conclude in which way the current system can change to cope with the evolution of space matters. This is necessary for the proper discussion of space matters because these matters cannot simply be divided between military and non-military, but are interrelated.
