Introduction: Under the influence of economic globalization, many enterprises are seeking more markets in developing countries, and more Chinese business expatriates are being sent to work in host countries. This study explores Chinese business expatriates' communication experience and identity work in three African countries, and their perceptions of the functions of English or the local language in transnational business communication. About the case: This article explores the following research questions: 1. How do Chinese business expatriates experience their cultural and national identity when using a foreign working language in a host country? 2. How do Chinese business expatriates evaluate the functions of a foreign language in their transnational communication? 3. What suggestions can be provided for future business expatriates and their transnational/globalizing companies? Situating the case: The process of identity construction and business expatriates' identity work in a host space are interpreted in the context of Hofstede and Hofstede's acculturation curve. Other key concepts related to transnational business communication, including third space as defined by Bhabha, are also addressed. Methods/approach: Using a case study approach, the researchers examine four participants' transnational business communication experiences and interpret their identity work through the data collected in the form of interviews. Results/discussion: The researchers find that the business expatriates realized the importance of English or local language communication competence in a transnational business space, although they still kept their Chinese cultural and national identity. Conclusions: This study contributes to transnational business communication by helping professionals to understand the language and cultural challenges faced by Chinese business expatriates, and offers suggestions for globalizing companies that send employees to host countries.

Chinese people have actively engaged in transnational and cross-cultural business activities in recent decades. Some Chinese people have moved their business activities to overseas countries, in particular, to developed countries. Some of them have migrated and settled down in a host space. About the case: This study aims to examine the identity work-in particular, the construction of a hybrid identity-and the business communication of a Chinese-Australian migrant, Jack, from the perspective of Chinese researchers. Situating the case: The communication characteristics of Chinese people are reviewed, and some factors related to identity work are examined. These interrelated strands provide a foundation for analyzing Jack's business communication and identity work in a host context. Research questions: (1) As an immigrant, how has Jack managed his identities in his business communication with self and Others during his life experience of more than 20 years in Australia? (2) Has Jack achieved a hybrid identity that enables him to switch his identities as he confronts the communication challenges of business situations? (3) What forces affect Jack's everyday business communication and identity work as a Chinese-Australian migrant in Australia? Methodology: Theories are applied to analyze anecdotes relating to the business communication and identity work of the migrant chosen for this case study. The first author is positioned as a cultural insider and ethnographer, observing, experiencing, and reflecting on some episodes in Jack's everyday business communication and identity work. The second author's informed input as an outsider to the case study provides interpretation of data and adds balance and a measure of objectivity. Results: Jack's communication with self and cultural Others is presented and analyzed to examine his complicated identity work in a host business arena. His shifting hybrid identity helps him to cross the border of his host culture and obtain privileges in business competition. These stories reveal that Jack's identity is continually changed and reconstructed as he builds social and cultural capital in his new business arena. Conclusions: This study captures characteristics of the transnational and cross-cultural business communication practices of Chinese migrants from the inside looking out, and it suggests that identity work is an ongoing and complex project, and that stereotypes should be avoided in transnational and cross-cultural business communication practices.
