A/HRC/11/L.11 page 26 10. Acknowledges that, in least developed countries and in several low- and middle-income countries, unsustainable levels of external debt continue to create a considerable barrier to economic and social development and increase the risk that the Millennium Development Goals for development and poverty reduction will not be attained; 11. Recognizes that debt relief can play a key role in liberating resources that should be directed towards activities consistent with attaining sustainable growth and development, including poverty reduction and the achievement of the development goals, including those set out in the United Nations Millennium Declaration, and therefore that debt relief measures, where appropriate, should be pursued vigorously and expeditiously, ensuring that they do not replace alternative sources of financing and that they are accompanied by an increase in official development assistance; 12. Recalls once again the call on industrialized countries, as expressed in the Millennium Declaration, to implement the enhanced programme of debt relief for the heavily indebted poor countries without further delay and to agree to cancel all official bilateral debts of those countries in return for their making demonstrable commitments to poverty reduction; 13. Urges the international community, including the United Nations system, the Bretton Woods institutions and the private sector, to take appropriate measures and actions for the implementation of the pledges, commitments, agreements and decisions of the major United Nations conferences and summits, including the Millennium Summit, the World Conference on Human Rights, the World Conference against Racism, Racial Discrimination, Xenophobia and Related Intolerance, the World Conference on Sustainable Development and the International Conference on Financing for Development, in particular those relating to the question of the external debt problem of developing countries, in particular of heavily indebted poor countries, least developed countries and countries with economies in transition; 14. Recalls the pledge contained in the Political Declaration annexed to General Assembly resolution S-24/2, adopted on 1 July 2000 by the Assembly, to find effective, equitable, development-oriented and durable solutions to the external debt and debt-servicing burdens of developing countries;
