Not at all wierd, China has been a strong supporter of Palestinian liberation for over half a century, and Muslims in China are quite happy. I'm assuming you're referring to the western allegations of genocide in Xinjiang, though there's pretty much no actual evidence for it. The best and most comprehensive resource I have seen so far is Qiao Collective's Xinjiang: A Resource and Report Compilation. Qiao Collective is explicitly pro-PRC, but this is an extremely comprehensive write-up of the entire background of the events, the timeline of reports, and real and fake claims.

I also recommend reading the UN report and China's response to it. These are the most relevant accusations and responses without delving into straight up fantasy like Adrian Zenz, professional propagandist for the Victims of Communism Foundation, does.

Tourists go to Xinjiang all the time. You can watch videos like this one on YouTube, though it obviously isn't going to be a comprehensive view of course.

Adrian Zenz, is that you?

If Israel treated Palestinians the way China treats its Muslim population, it would be held up as the platonic ideal of compassion and goodness, and Netanyahu would be awarded every noble peace prize for the next century
