I (an American) ran into this. Centcom was (is?) doing things like whitewashing the No Gun Ri massacre on Wikipedia - http://en.wikipedia.org/w/index.php?title=No_Gun_Ri&diff=185... .

That IP used to resolve to n-mnstci-142.mnstci.iraq.centcom.mil . In my spare time I add information to Wikipedia, then I am taxed and some propaganda minister in the military, being paid by my taxes, gets rid of what I said and does some Orwellian rewrite if history.

These Chinese efforts seem skin to what the US government has been doing.
