ABSTRACT: This paper attempts to offer a new understanding of the âconstructedâ nature of ethnic identity and ethnic-relations in Southeast Asia. Using Malaysia as a case, I first sketch the history of Indian and Indonesian diasporic cultural flows into and influences on the peninsula Malay identity from pre to post-European colonisation. Second, I point out how state-led mediatised essentialising of the  peninsula âMalayâ as territorial and indigenous (bumiputra) appears to have led to the inclusion and exclusion of the pre and post-colonial Indonesian migrant at various moments in the process of negotiating Malay identity, making of an urban Malay-Muslim and the re-making of a capitalist Muslim-Malay. Third, I argue and maintain that the process of âotheringâ in multicultural Malaysia seems triggered by âontological insecurityâ and âde-traditionalisationâ â as pointed out by Anthony Giddens (1990) â and the hegemonic construction of Malay(sian) identity. Finally, the national culture and identity has been described as a form of imaginative identification as an idea that is simultaneously one of inclusion (e.g. âBangsa Malaysiaâ or Malay plus Indonesian) that provides a boundary around âusâ and one of exclusion (e.g. âbumiputra/bukan bumiputraâ or Malay minus Indonesian) that distinguishes âusâ from âthemâ, where race (the Malay) is symbolically expressed as national and territorial, constructed differently and distinctively.Key Words: Diaspora, media, culture, identity, ethnicity, Islam, Indian, Indonesia, and Malay(sia).About the Author: Assoc.
