Firstly, there is no such thing as a "western way of thinking."
Secondly, none of the media are 100% impartial. The good old days of impartial BBC reporting went out the window a while ago. However, I think it remains the most impartial (English) media today. Along with that, the tone of voice of BBC reporters is still quite pleasant. CNN clearly reflects the way they "believe Americans should think", and is, in my humble opinion (LOL), awfully self righteous.
VOA is trash!
If you are looking for trustworthiness, forget it. It's an old saying, but look for virtues in yourself first, before pointing the finger at others.
There are other international broadcasters, but none of them attain the high standards of the BBC.
