This issue, in a New York Times article, is relevant to us also.

Most recently we visited this issue with the 2011 Chinese protests article on the English Wikipedia where our article could easily have been more influential than anything that was happening in China. There were also issues with this on the Chinese Wikipedia, but I don't know details.
