“…In addition to the above, there is a body of research on the political activities of diasporic communities which includes both newer work on diasporas as political actors and earlier work that examined the impact of migrant interest groups and ethnic lobbies on American foreign policy (see Huntington, 1997;Mathias, 1981;Tucker et al, 1990;Uslaner, 1991;Weil, 1974; see also Shain, 1999, for diasporas as promoters of US interests abroad). While earlier work treated diasporic communities as 'ethnic groups' operating within the state, the increasing politicization that many ethnic communities have undergone in recent years and the growing awareness of the importance of diasporic ties with the sending country have encouraged researchers to also pay attention to these groups' links with their countries of origin, a dimension that was largely ignored until recently (Constas and Platias, 1993;Hockenos, 2003;Shain and Barth, 2003;Winland, 1995;Ostergaard-Nielsen, 2002).…”
