When I Google search for bias in AP’s coverage of Israel-Palestine, all of the sites I encounter claim they have highlighted harm to the Palestinians more than threats to the Israelis. I feel like this isn’t what you’re talking about though? This level of bias (highlighting the concerns of one side over another) is still substantially less egregious than what you are accusing them of: just getting facts blatantly wrong/ opposite of the truth in Xinjiang.
Look, without speaking Mandarin, traveling to Xinjiang, and having access to all the sites in question, I can’t really know what’s happening there. The best any outsiders can do is try to study through the sources available and pick out who we trust.
I trust the AP. As an organization, they trade on their reputation for quality and unbiased coverage. When I read pieces by them of extremely controversial events in the US, they give only facts. I am absolutely going to trust them more then an unsigned document, hosted by a site I don’t know, that largely engages in character assassination of names I don’t even recognize.

If the Chinese killed them, it’s relevant to a discussion about China. If the US killed them, it’s not relevant unless it caused some reaction within China.
You cannot engage about the rightness/ wrongness of Chinese domestic policy without stopping to bash the United States. That is Whataboutism.
Perhaps your goal is really just to point out America’s hypocrisy, but you certainly go out of your way defending China’s actions if that is your goal.
