This article examines the extent to which overseas Chinese educators at Confucius Institutes (CIs) in Thailand act as representatives and practitioners of Chinese national identity. Though working for the state, CI teachers promote Chinese language and culture according to their own perceptions. In this paper, participatory observation and in-depth interviews were employed to assess how CI teachers in Thailand articulate their Chineseness and national identity. The findings show that (1) banal national sentiment was an important expression of the CI teachers' national identity, in terms of psychological attachment and ingrained behaviors; (2) pragmatic identity politics are used to distinguish various contributors to the CI; (3) the materialization of Chinese national identity recontextualizes the country via national symbols and cultural activities. The intricacy of the everyday activities of CI teachers illuminates the trans-nationalization and localization of Chinese national identity, which constitute the “doing” of the nation that the imaginary Chinese community in Thailand represents not just a government-endorsed national identity but also the CI teachers' creation of tradition.
