Come on muhfuhkuha, you're taking this out of context. The author is saying that China is an accomplice in crimes committed by NK because it expels refugees who face imminent threat in NK, thus making China an accomplice. China cannot push escapees back into shark waters and say "I am not the shark", I'd say "Yes China, but you kind of fed this person to the shark."

The US has a very generous amnesty and refugee program, and if you can prove in court that you will be killed or prosecuted in your home country then you're granted residency. I personally know 3 people who have undergone this process. If they tried the same in China, they would have been swung right back over the border.
