In order to figure out your question, you need to think about what you find most interesting in the articles you have read. Furthermore, you want to ask something that isn’t already known (even if the answer is already in the existing data).
One thing that I personally find interesting is the uneasy balance between the ideal of academic freedom on the one hand and the existence of Confucius Institutes on many campuses. You’ve probably read about these already, but there are at least two open questions here.
The obvious one is whether the politically motivated self-censorship that these institutes engage in is something that universities can support without undermining their own values. If they really are propaganda centers, then it seems allowing them on campus is more likely to close minds than open them. Yet shutting them down, especially when they offer resources that may not be available elsewhere, may seem to be a different kind of censorship (or at least a way of cutting students off from some avenues of learning).
The second is what the long term consequences are of allowing these institutes to train future teachers. For one, the training offered may build constraints into the very way that these teachers think (meaning they may self-censor without even realizing it or simply be trained to avoid certain subjects or lines of thought). But also, the power that these institutions have over hiring, firing, and recruitment could lead to only those with a particular mindset being allowed in to begin with. This filtering process is its own kind of censorship.
