UN General Assembly
1961

It is now generally recognized that developing countries are morally and economically justified in extending a certain degree of protection to infant industries against competition from the industrialized countries if they are to make any progress at all in their plans of industrialization. No comparable justification can be given by developed countries for protecting a few sectors of their economies against competition from under-developed countries, enjoying as they do a high standard of income, also a high degree of resource mobility in their diversified economies.
