None whatsoever. Because 1) I do not hold people collectively responsible, and 2) even if acting in good will and on voluntary basis, this would mean I believe foreigners should be able to dictate to other countries how they should work within their own borders. If there is indeed a violation of international treaties, escapees should be able to sue China in Brussels or NYC at the International Criminal Court. This is the proper way to deal with such issues: by shining a bright light and not engaging in "feel good" actions that will be at best futile, at worst increase anti-Chinese racism.
