IOM launched its International Dialogue on Migration (IDM) at the fiftieth anniversary session of the IOM Council in 2001, at the request of the Organization’s membership. The purpose of the IDM, consistent with the mandate in IOM’s constitution, is to provide a forum for Member States and Observers to identify and discuss major issues and challenges in the field of international migration, to contribute to a better understanding of migration and to strengthen cooperation on migration issues between governments and with other actors. The IDM also has a capacity- building function, enabling experts from different domains and regions to share policy approaches and effective practices in particular areas of interest and to develop networks for future action.
