In terms of the number and the scale of detentions, there is very credible evidence and information about the mass detentions in these education camps, and it is very difficult for a government to claim that all of the information is fabricated and that there aren't widespread and systematic abuses occurring, both in the detention facilities and among the everyday population in Xinjiang. That is just simply unavoidable.
The question I would have for the government really is, if they are not willing to acknowledge the accuracy of the reports, would they at least call on the Government of China to allow independent investigators to enter Xinjiang and assess and investigate whether those reports are credible or not? Human Rights Watch, for example, has no access to Xinjiang, nor do journalists. Those who have been able to enter are only able to enter in a very monitored fashion, which in many ways actually puts at risk the individuals they are interviewing. If there are issues of accuracy, I would call on this government to request an independent assessment and urge China to agree to one.
