This research report deals with the subjects of the extension of foreign investments into emerging countries. the particularity nowaday is the internationalisation of strategic activity such as R&D. Many inquiries can be rise since, multinational technology activities are not anymore limited to simple adaptation activity. Emerging countries like China are emplementing their own technology trajectories, so as to attract more and more foreign R&D. This has to do with a change in the behavior of the foreign multinational because the conventional model not only cannot predict the internationalisation of R&D into emerging countries, but even when it does so, it assumes that the suitable technology activies into emerging countries are those limited to adapt home technology. I explain foreign multinational behavior by extending HEWITT (1981) model of internationalisation of R&D. I found that most of the R&D going to emerging countries is for development and adaptation. But the question still remains to know why some multinationals are extending their innovative activities into emerging countries and create regional innovation hubs (choosing one country to play the role of main regional innovation hub). I assume that multinational are both technology exploiting and technology explorer, their motivation are more than sharing their technology with emerging countries, but they aim at exploring technology opportunities in other for them to differentiate and innovate and stay a breath of what the competition is doing. In this part the research all the statistics and indicators show that China is playing the leading role with a technology trajectory above those of the three others countries. This seems to explain why China instead of India is the most attractive destination of foreign investment in production and in R&D.
