Slavery was wrong even in the 1700s and and 1800s. I wish it hadn't happened, but until we have a time machine there's not a lot we can do about it.
Just because the US has committed major sins in the past doesn't mean we should be slap-happy about other countries repeating those sins.
It might be "sanctimonious", but I don't think "I'm against slave labor everywhere" is an especially brave take.
I am not sold that this is a real thing in China in the first place. The main citation I can find is for the U.S. fake story about Xianjiang that is debunked on cursory inspection.
