Meeting others abroad and/or online is considered important in the broad field of intercultural communication education (amongst others: international education, minority and migrant education, but also teacher education, language education) to test out one's learning about interculturality. For several weeks, a group of university students from China and a group of local and international students studying at a Finnish university met regularly online to talk about global educational issues. Using a specific lens of interculturality, which focuses on the discursive co-construction of identities, we explore their initial interactions, how they deal with the uncertainty and potential awkwardness of their very first encounters, before they start working on their educational tasks. Based on the students' self-disclosure (practices, thoughts, identity construction), and adopting a dialogical discourse analysis, the authors examine their co-construction of interculturality. The results show that the students try to facilitate interculturality while promoting it together more or less successfully. Reasons are discussed. The authors argue that research on the underexplored case of online initial interactions, which represent crucial moments in establishing and negotiating interculturality, could provide important research and pedagogical input for intercultural telecollaboration.
