They probably are. They probably aren't covering them in English though, it's not for English speaking audiences. China, as an example, has very publicly chastised the US for its countless human rights violations over the years. Many non-Western countries have.
You're talking about my case here, but your case basically boils down to "I don't see countries reporting on Western crimes in English, so it must not be happening" which...is certainly an argument you could make. Western countries have a horrible track record of reporting on their own crimes, and non Western countries probably aren't writing lots of English articles for English speaking audiences because that isn't who their readership is. I guess if you're fluent in some other languages and spend a lot of time reading non Western media in non-English languages then you'd have a stronger argument here. I kinda doubt that though. And I bet if I did start pulling out less Western media sources that do report in English like Al Jazeera or RT I would be immediately called out for parroting anti-Western propaganda. It's a real catch 22.
My argument is "Western governments fund propaganda efforts against their perceived competition, so stop parroting it as if it's objective fact." They don't even hide that they're doing it, it's not like this is some nutter conspiracy theory. There is plenty to be critical of China for, but "Chinese Embassy Doing Embassy Things" isn't one of them and only serves to fuel anti Asian racism and propaganda.
