UN General Assembly
1959

12. It is quite clear that the drafters of the Charter did not intend everything to be done in the United Nations. The Charter is full of references to activities which not only can, but even should, be conducted outside of the United Nations itself. For example, under Article 33 of the Charter, parties to any dispute are told first of all to seek a solution by negotiation, inquiry, mediation, or other peaceful means. There are a number of references to activity outside the United Nations — for example, reference to regional arrangements and to the right of individual and collective defence. Such references illustrate that it was never intended at San Francisco that every act of international negotiation and of international conduct should be made through the United Nations.
