Absolutely incredible reporting. The risks taken by the sources both at the factories and within North Korea defy comprehension for anybody lucky enough not to fear that speaking out will endanger their family.
That evidence all supports the argument that the PRC and Chinese companies are complicit in violating sanctions.
Further, it is telling that the NK government and their Chinese co-conspirators actively fight investigations. See the literature spread to workers threatening punishment for talking to reporters.
And this should surprise absolutely no-one. It's like it's 1980's Wall Street over there, and whatever makes a buck is what they do.
> Most of the people also don't care
I think it may be quite the opposite, albeit usually not genuine "caring", rather just "focusing". Whether nations want to redirect people's attention away from problems at home, or people want/let their attention redirected, they'll focus more on the crap happening in another country. An enemy or an issue are always created somewhere far away, something as contrasting as possible with the apparent situation at home.
Take the example of prisons and prison labor in the US. People know millions are imprisoned at home, many forced to work, with inhumane conditions. But that's a bitter taste when they know it's at home, that it's a democratic country, that this could be changed but isn't. So it's made better by looking at how much worse it could be.
It's an easy mental and moral release and people need one especially when there's a discrepancy between the image they have of their country and the reality. The bigger the discrepancy, the easier and more attractive it is to look at the speck/plank in someone else's eye.
This happens everywhere in the world because it's human nature: it's where people's desire to comfort their conscience and leaders' desire to manipulate that intersect.
Your reply seems out of place.
