This Toolkit has been developed by IOM in collaboration with UNCTAD with the support of the European Union under the Mainstreaming Migration into International Cooperation and Development (MMICD) project. In the Toolkit, we explore how migration relates to the following sub-sectors: (i) regional integration and trade policies, (ii)customs and trade operations, (iii) small scale cross-border trade, (iv)private sector development, financing and innovation. It provides practical information and tools to help development practitioners integrate migration into private sector development and trade interventions.
