In 1965, in resolution 2037 (XX), the General Assembly endorsed the Declaration on the Promotion among Youth of the Ideals of Peace, Mutual Respect and Understanding between Peoples. From 1965 to 1975, both the General Assembly and the Economic and Social Council emphasized three basic themes in the field of youth: participation, development and peace. The need for an international policy on youth was emphasized as well. In 1979, the General Assembly, by resolution 34/151, designated 1985 as International Youth Year: Participation, Development, Peace. In 1985, by resolution 40/14, the Assembly endorsed the guidelines for further planning and suitable follow-up in the field of youth. 2/ The guidelines are significant for their focus on young people as a broad category comprising various subgroups, rather than a single demographic entity. They provide proposals for specific measures to address the needs of subgroups such as young people with disabilities, rural and urban youth and young women. 14. The themes identified by the General Assembly for International Youth Year: Participation, Development, Peace - reflect a predominant concern of the international community with distributive justice, popular participation and quality of life. These were reflected in the guidelines, and they represent overall themes of the World Programme of Action for Youth to the Year 2000 and Beyond as well. 15. The Programme of Action also builds upon other, recent international instruments, including the Rio Declaration on Environment and Development, adopted by the United Nations Conference on Environment and Development, 6/ the Vienna Declaration and Programme of Action adopted by the World Conference on Human Rights, 7/ the Programme of Action of the International Conference on Population and Development, 3/ the Copenhagen Declaration on Social Development and the Programme of Action of the World Summit for Social Development, 4/ and the Platform for Action adopted by the Fourth World Conference on Women. 5/ 16. The Programme of Action is drawn from these international instruments generally and specifically related to youth policies and programmes. The Programme of Action is significant because it provides a cross-sectoral standard relating to both policy-making and programme design and delivery. It will serve as a model for integrated actions, at all levels, to address more effectively problems experienced by young people in various conditions and to enhance their participation in society. 17. The Programme of Action is divided into three phases: the first phase focused on analysis and on drafting the Programme of Action and on its adoption by the General Assembly at its fiftieth session, in 1995; the second phase is concerned with world-wide implementation of the Programme of Action 6/ Report of the United Nations Conference on Environment and Development, Rio de Janeiro, 3-14 June 1992, (A/CONF.151/26/Rev.1 (Vol. I and Vol. I/Corr.1, Vol. II, Vol. III and Vol. III/Corr.1)) (United Nations publication, Sales No.E.93.I.8 and corrigenda), vol.
