The search for some means to terminate the Vietnam conflict by negotiation has given rise to certain anomalies in the application of the law and procedure of the United Nations and of the existing regional arrangements affecting Southeast Asia. It has also revealed the existence of a lacuna in the provisions of these international instruments governing the discharge of peacekeeping functions. This, however, is not the case in respect of the International Commission for Supervision and Control in Vietnam which constitutes the only tangible instrument of the Geneva settlement specifically created to fulfil, on a continuous basis, the tasks of control, observation, inspection, and investigation connected with the application of the Cease-fire Agreement for Vietnam.
