The Trump administration should sanction China over its unjust detention of three Canadian citizens.

The need for such action is informed by two factors. First, the Canadians are detained without any objectively justifiable cause. Second, at least one of those detained, Michael Kovrig, is apparently being held in incommodious conditions. According to the Financial Times, the lights in Kovrig’s room are kept on 24 hours a day. This obviously affects his ability to sleep.
