As I posted in the discussion page of that page, for calling Chinese state media as propaganda, I can say the same for the western media.  So unless you have something that proves the news as fake, such claim would constitute your original research.  In fact, during last year's Tibet incident, western media has shown plenty of mis-inform mis-represent information (see anti-cnn.com for plenty of hard facts) to support their bias.

At the same time, it is also ridiculous (and insulting) to consider it as propaganda.  Should 9/11 report by the U.S. government be considered as propaganda? given its statements on WMD in Iraq are all lies?  You can cite western media with DIRECT evidence (rather than quotes or unaccountable statements) to dispute it, but removing the item simply because you think it is "propaganda" is POV.
