I think it is very hard to get a "detached analysis". For politic issues like this, it is inevitable that everything you read will be both incomprehensive and biased, and filled with propaganda. Probably you can find a "detached analysis" 50 years later, but not now.

That said, if you can read Chinese, I found Taiwan's monthly "mainland report" interesting to read [1]. Of course it is far from a detached analysis, but it's not very polarized (imo) and it contains interesting information.
