It is probably quite likely that someone has asked this question before, however the search function doesn't throw anything up and it is actually quite difficult to search for!
Simply put, I have noticed the sentence structures 在...中 / 在...下 / 在...上 and am not entirely sure what they mean， though I can limit their possible meanings from context. For example:
在中国和印度两个大国的努力下 must mean something like "due to" or "as a result of" or "in the process of" or "thanks to".
However, I don't know what it is precisely enough to do use it confidently myself. The same goes for 在...中 and 在...上.
If someone fancies giving a bit of an insight, it'd be much appreciated!
