Attention to international migration at the global, regional and national levels has been increasing since the holding in 2006 by the General Assembly of the High-level Dialogue on International Migration and Development. In response to General Assembly resolutions 63/225 and 65/170 on the issue of international migration and development, which encouraged the adoption of a balanced, coherent and comprehensive approach to international migration and development and invited relevant organizations of the United Nations system to provide input to the High-level Dialogue on International Migration and Development, to be held by the General Assembly in 2013, CEB took up the issue at its spring 2012 session. To ensure system-wide coherence and coordination in submitting input to the High-level Dialogue on International Migration and Development, the United Nations Population Fund and the International Organization for Migration, in collaboration with the Global Migration Group, would lead an inter-agency consultation process with a view to preparing an analysis of opportunities and challenges of international migration, as well as draft outcomes and recommendations on migration as an input to the preparatory process for the High-level Dialogue.
