United Nations peace-keeping is presently being faced with dynamic new challenges. The concept of peace-keeping is rapidly expanding, operations are being entrusted with new and innovative tasks, and are increasingly being deployed in intrastate conflicts. As the functions of peace-keepers vary, so too does the role and conception of peace-keeping. The new tasks entrusted to peace-keepers have brought with them new problems and difficulties. Controversial recent operations, such as those in Somalia and the former Yugoslavia, have particularly raised the issue of impartiality in the context of UN peace-keeping. Impartiality is traditionally a distinguishing feature of peace-keeping operations, yet its meaning and status remain unclear.
