While policy transfer studies traditionally observe top-down processes (Delpeuch 2009; Stone 2012), this paper analyses an original circulation of a territorial policy. Using the 'translocal' concept drawn from migration studies (Smith and Guarnizo 1998, 10), I argue new spaces of policy circulation can be found probing the political co-presence of diasporas : local-yet transnational-actors in their places of residence and origin. The paper is structured by the combine analysis of decentralization processes and organized diasporas, both key to the circulation of policies.In France and Francophone Africa, decentralization processes put municipalities at the center of policy making processes in technical sectors (Fay et al. 2006). To strengthen their technical, financial and political ressources, French municipalities grouped in intermunicipalities to implement efficient common territorial policies. With scarce resources, Comoran and Malian local authorities adopted the same model, through international cooperations with diasporas and French municipalities. While Malian and Comorian diasporas are known to play a key role in national and local policies of their country of origin, their role in France is far less studied. In Paris suburb cities with important foreign population, local authorities develop strategic relations with diasporic organizations to foster their political base (Soukouna 2016). They are inclined to meet diaspora’s objectives to do so, international cooperation included. The paper therefore analyses the creation and circulation of the intermunicipalities in eastern Paris region, Mali and the Comoros, as the result diasporas’ political mobilizations, intertwining territorial public policies. Diasporic organisations and intermunicipalities are followed through qualitative mixed materials (about 20 semi-structured interviews, observations, and archival processing). The international comparison method allows to scrutinize local and sectoral public policy adoptions while mobilizing Diaspora Studies’ definition of the transnational concept. I question the consequences of national decentralizations on both politics and policy making, with new policy models transferred by diasporas linked to two countries by residence or origin. While seeing diasporas and local authorities as new actors of policy transfer, the paper enlightens new sub and trans-national procedures for public policy circulations.
