They have a love/hate relationship with foreign scholars. They needed them to give the university credibility, but they are not really allowed to prosper. Among their tactics (1) keeping them on short-term contracts, renewed ONLY after the previous one ends. That way one cannot apply for grants, establish a research program, etc. This occurs regardless of productivity, even if despite the conditions, you are more productive than people who have been there forever. (2) Keeping foreign scholars isolated, often in separate rooms, with each other, sometimes even in other buildings. The argument is so that hey have someone to speak, but the consequence is that they are excluded from any type of interaction or decision, or even party announcements.
