The problems within the United Nations system represent only part of the problem of bringing greater order, coherence and coordination into international economic and social activities as a whole, among UN and non-UN, world-wide and regional organizations and between UN bodies and the bilateral aid activities of individual 'donor' Governments. To separate the part from the whole has great disadvantages, since duplication and even conflict between UN and non-UN bodies are themselves among the most serious and conspicuous causes of criticism, and solutions may well affect the structure, functioning and programmes of organs within, no less that those outside, the UN system.
