UNITED NATIONS (May 2): THE UN General Assembly last night approved a controversial plan for a new world economic order despite objections from Western industrialised countries. The Assembly's special session on the world economic crisis also adopted an action programme designed to help developing countries hardest hit. Earlier the United States announced the withdrawal of its planned U.S.$4,000 million aid programme for developing countries worst affected by soaring prices. There was no explanation for the U.S. move, but it was assumed the U.S. felt its plan had been made redundant by the Assembly's decision, the U.S. ambassador, Mr John Scali, said: 'Words cannot feed the starving, nor help the impoverished. This moment demands more of us than words - more of us than promises that may materialise many months from now, if ever.' The U.S. delegate termed the declaration of principles and the action programme 'significant', but he said they did not represent a consensus of Assembly opinion. 'To label some of these high controversial conclusions as agreed is not only idle, it is self-deceiving,' he said. 'In this house, the steamroller is not the vehicle for solving vital, complex problems.' This appeared to be reference to the powerful group of developing states whose two-thirds majority assures the passage here of their proposals. Western sources said the group had insisted on the adoption of the Declaration of Principles and action plan as a single package, quashing any idea of a formal vote, which would have countries with reservations to abstain. The document of expected to be on a par with such historic pronouncements of the world body as its Universal Declaration of Human Rights.
