I’d argue that most of the numbers you’ll find apply to the US, not to the west. The US is pretty much known everywhere for having third world shortcomings on specific areas.
The United States ranks as one of the worst countries in the world for human trafficking
Despite a common and widespread misconception, human trafficking is not just a problem outside the US. It also happens here, within United States borders, and in every state.
Less people incarcerated is good, how the prisoners are treated is another issue entirely and of course China can and should be heavily criticized for that.
But penal labor for literally cents/day or private prisons as a source of profit or the death penalty are something that the US, above all, should be able to improve on, before lecturing other countries over human rights.
Let's talk about
“Guantanamo Bay is a site of unparalleled notoriety, defined by the systematic use of torture, and other cruel, inhuman or degrading treatment against hundreds of men brought to the site and deprived of their most fundamental rights.”
This is a statement from "The Office of the High Commissioner for Human Rights of the United Nations".
What have the consequences been? Nothing. Literally nothing has changed!
People have been detained there for years, most of them without any charges, denied of the right to a due process, only because they were Muslims.
39 of those men are still kept captive there as of today, 20 years later, 27 of them have never been charged with any crime, the others have been cleared for transfer years ago, but are still there.
Imagine if China did something like that what the US would be saying about it.
That's the moral short circuit: if it's wrong it must be wrong for everybody, especially for those claiming to hold in high regards human rights, not only if China or Russia do it.
Some source to backup this number? Are they actually in prison?
IMO the fact that we should be skeptic about China official stats means that we should also refrain from throwing random numbers at the wall hoping it will make China look bad.
BTW, two wrongs don't make a right, it's not about what they do wrong, it's about what we do better, like for example, is Guantanamo acceptable in a western democracy?
Compare China homicide rates to USA.
Or China incarceration rate to USA incarceration rate.
