So do most sanctions no matter how justified. The well being of those people are the responsibility of the Chinese government. It would be pretty easy to allow transparent media reports in the province if one wanted to show the world that there is nothing bad going on.

What the US (or anyone else) does in any other corner of the world is a separate topic and uninteresting in this context.
