UN General Assembly
1957

110. The United Nations was conceived as the chief instrument of peaceful coexistence, as the noblest means of securing the coexistence of peoples with differing political systems. The Member States were to achieve this goal by mutual respect for territorial integrity and sovereignty, by non-aggression, by non-interference of any kind - political, economic or ideological - in the domestic affairs of any other country, by equality and policies of mutual benefit, in a world, by the fostering of a spirit of peaceful and creative emulation.
