UN General Assembly
1958

160. In the same spirit that inspired the above- mentioned provisions of American international law, the United Nations has declared against any intervention in economic affairs. General Assembly resolution 200 (III), relating to technical assistance for economic development, lays down that technical assistance shall not be a means of foreign economic and political interference in the internal affairs of the country concerned and shall not be accompanied by any considerations of a political nature. This principle was confirmed in resolution 222 A (IX) of the Economic and Social Council. 161. We therefore consider that intervention constitutes an act of aggression, which may be direct or indirect according to its character and the means used, and that the only intervention which is legally justified is collective intervention as authorized by Chapter VII of the Charter, for the maintenance of international peace and security.
