UN General Assembly

21. We agree, as we have often repeated in various international documents that the primary responsibility for the economic development of the developing countries rests upon those countries themselves. But there is another fact, which applies in no case more than it does to the least developed countries: the efforts of those countries for development cannot succeed without urgent, comprehensive and sustained international assistance and co-operation. That fact has been recognized by the developed as well as other developing countries in numerous documents, the most recent of them UNCTAD resolution 62 (III), which contains specific commitments and measures. It is high time to ascertain to what extent these promises are going to be kept.
