In the twenty-first century, Asian American studies has turned increasingly toward diasporic and transnational frameworks, even as some scholars have raised concerns about the loss of an Asian American identity and politics grounded in cultural nationalism. Drawing in part on the work of Paul Gilroy, I propose a new theory of “Asian diaspora” in which “Asian” identity emerges from a dialectic of national and transnational forces. Since the 1970s, this category of Asian identification has circulated among the United States, Canada, and Australia, white settler colonies with histories of Asian immigration and exclusion. The work of Asian poets in these locations registers, in content and form, the history of diaspora that gives rise to Asian identity.
