If you haven't heard of this guy, he's a fellow at 'Victim of Communism Foundation Memorial', set up and paid by US.
Anecdotally, private businesses in China very much dislike taking in labor transfers (more or less a gov initiative) - because they had to provide housing, specific food (halal, etc), and even religious facilities while paying the same. The labor quality is not nearly as high as one on the market. This is essentially China's answer to increase employment for the remote regions.
Of course they would 'suggest the transfers have coercive elements.' The same pay and benefits simply doesn't exist in the region, why would anyone want to go? /s
