while it's definitely pro china, I still find it to be by far the most valuable news television.
It focuses on Africa and Asia, which I otherwise hear very little about. The value of the news for me is mostly not whatever the news is, but the facts surrounding the news.
For example when they covered the election in Senegal, I learned a ton about Senegal as a result. The news about the election was not the important part in this case, it was learning about the country.
