Google not only censors content in China, it also seemingly censors the idea that it censors things. See this page at Google (courtesy of the all-powerful Google cache) for what the company used to say about search censorship, and then click here to see what the same URL now tells you.
[Update] Interestingly, Google has now removed the old “we don’t censor” page from the Google cache, and has replaced the old page with some revised text. Here is what Google used to say about search censorship:
Google does not censor results for any search term. The order and content of our results are completely automated; we do not manipulate our search results by hand. We believe strongly in allowing the democracy of the web to determine the inclusion and ranking of sites in our search results.

And here is what Google now says about search censorship:
It is Google’s policy not to censor search results. However, in response
to local laws, regulations, or policies, we may do so. When we remove
search results for these reasons, we display a notice on our search
results pages. Please note: For some older removals (before March
2005), we may not show a notice at this time.
