The Global Forum on Migration and Development (GFMD) is a recent initiative of the United Nations Member States to address the migration and development interconnections in practical and action-oriented ways.
 It is an informal, non-binding, voluntary and government-led process that marks the culmination of more than a decade of international dialogue on the growing importance of the linkages between migration and development.
 It reflects the progressive acknowledgement of the limits of a strictly national approach to migration questions and implications at a global level in an intergovernmental framework.
 In view of the societal implications of these issues, civil society representatives have also been involved from the outset in this process.The GFMD Business Mechanism, endorsed at the 2015 GFMD Summit in Istanbul, brings the voice of business to the forum.
 There is clearly a mutual interest between governments, the private sector, and civil society, to promote more transparent, effective and humane migration policies, taking into accounts labour market needs.
 The International Organisation of Employers (IOE) and the World Economic Forum Global Future Council on Migration coordinate the work of the GFMD Business mechanism.
 Together they form the Business Advisory Group.
 The GFMD Business Mechanism is housed at the IOE in Geneva.
