The internationalisation of the Portuguese language has become a priority for academic institutions of different Portuguese-speaking countries which are trying to adapt to the current context of globalisation and ubiquitous communications through digital media. In order to achieve it, several challenges should be faced, namely providing international students with resources aimed at helping them improve their Portuguese while fostering its use in academic and scientific contexts. This can be done by identifying, creating and editing high-quality teaching materials which bear in mind the sociocultural, political, economic and linguistic contexts; using the Information and Communication Technologies effectively in both face-to-face and online learning environments (International Institute of the Portuguese Language, 2010); and promoting the online learning of Portuguese as a Foreign Language in higher education settings through virtual learning environments. This paper explores the challenges brought about by the internationalisation of Portuguese and how computer assisted language learning - and, more specifically, the development of a virtual learning environment aiming at catering for the linguistic needs of international students in different institutions in Brazil, Portugal and elsewhere - could help face these challenges
