"The term,"economic and technical aid",was in the 1940s.In the 1960s,this was changed to "technical co-operation"as the donor,who offered aid,and the recipient,who received it ,took more seriously the mutual co-operation that was needed.From the early 1970s,two new dimensions in technical cooperation were evolved by UN:(i)the country programme approach and (ii)mutual technical co-operation among developing countries (TCDC).International co-operation programmes by National Science Foundation are discussed.
