This article examines Chinese cyberspace debates over the racial and national identity of a television show contestant Lou Jing, a biracial woman of Chinese and African American descent. We argue that the online commentary about her offers a productive entry point into contemporary Chinese cultural struggles over race. In particular, we consider how the Internet and other digital communication technologies are being mobilized as discursive sites for articulations of Chinese anti-black racism, as well as discursive sites of contestation, knowledge production, and cultural exchange regarding Chinese constructions of race and nationality.
