The Soviet regime ran a large system of forced labor camps. China currently runs a large system of forced labor camps. Horrible human rights violations occurred under the Soviet system and are currently occurring in China.

Here's a recent, quite representative, example of the sort of thing that can happen to someone in China:

"Chinese teacher sent to labour camp for earthquake photos" http://www.guardian.co.uk/world/2008/jul/30/chinaearthquake....

Excerpt:

  A Chinese teacher has been sent to a labour camp over his   
  internet photographs of schools that collapsed in the 
  Sichuan earthquake, a rights group said today.

  Liu Shaokun was ordered to serve a year of "re-education   
  through labour", according to Human Rights in China. The 
  system does not require a formal charge or criminal trial 
  and there is no appeal.
