China is taking thousands of Uighur children away from their parents and putting them into boarding schools designed to assimilate them.

This resembles what the US and Canada did to indigenous peoples during much of the 20th century. Public opinion made the US and Canada stop this, but in China public opinion is not allowed to exist.

Even fairly mild reproach of China for putting a million Uighurs in brainwash camps has discomfited China. Firm pressure might accomplish a great deal.

Perhaps Hong Kong should be the main target of the pressure, for now.
