The Declaration of Independence doesn't legally "apply" in the U.S. either. It's a historic document making certain philosophical arguments (inalienable rights, right to overthrow tyrannical government, etc.) and then applies that philosophy to a particular historical context. And, yes, inalienable rights apply in China. If it is good and proper to be offended by how someone is treated regardless of legal context, there is an implicit inalienable right. Ad absurdum, we expect freedom from rape, justice broadly defined, freedom from genocide, and many other things. If Elbonia passed a law saying lynching of minorities was OK, they'd be wrong. That's what makes the relevant rights inalienable.
