This chapter studies a wiki project that electronically links English students learning Business Chinese in the UK and Chinese students learning Business English in China. The focus is placed upon enhancing English/Chinese language skills and intercultural communication competence. Students' messages on the wiki illustrate that cultural values and cultural competence are important parts of business communication. The results of a questionnaire survey and a focus group interview indicate that the interaction between language learners and native speakers not only helped students improve each other's language, but also allowed them to understand the business norms and behaviours in another culture. The chapter concludes with a proposal that wikis can be a platform for enhancing language output and intercultural communication competence, if well designed and monitored.
