From October 2012 to June 2013, IOM, UNDESA and UNFPA organized, in collaboration with interested governments, five substantive meetings to prepare delegates and observers to the United Nations for the 2013 General Assembly High-level Dialogue on International Migration and Development. Four of the meetings focused on the themes of the four round tables decided upon in UN General Assembly Resolution 67/219, while the introductory meeting discussed the evolution of the global debate on international migration and development to date.
