From the conclusion of the UN report you linked:

Serious human rights violations have been committed in XUAR in the context of the Government’s application of counter-terrorism and counter-“extremism” strategies. The implementation of these strategies, and associated policies in XUAR has led to interlocking patterns of severe and undue restrictions on a wide range of human rights. These patterns of restrictions are characterized by a discriminatory component, as the underlying acts often directly or indirectly affect Uyghur and other predominantly Muslim communities.

But this is all just whataboutism anyway. We can be against human rights violations regardless of who is doing it and whether they condemn each other.
