The central theme for the vast majority of the members of the United Nations is the challenge of development and eradication of poverty, said the Prime Minister,Dr Manmohan Singh, in his address to the General Assembly in United Nations. "Globalisation has undoubtedly brought enhanced effectiveness and efficiency in economies, integrated market places, higher standards of living and a revolution in global connectivity. But there is also the phenomenon of widening economic disparities, both within and among countries," Dr Singh remarked.
