Star Wars was not vetted by any government officials for its ideological purity before publication, is the difference. Anything that is published in China, by definition is representative of the opinions of the Party.
For example, from http://gking.harvard.edu/publications/how-Censorship-China-A...
"Contrary to previous understandings, posts with negative, even vitriolic, criticism of the state, its leaders, and its policies are not more likely to be censored. Instead, we show that the censorship program is aimed at curtailing collective action by silencing comments that represent, reinforce, or spur social mobilization, regardless of content."

The point I was trying to make is that, a sweeping statement such as "Anything that is published in China, by definition is representative of the opinions of the Party.", simply isn't true.
It is not even true for the mainstream media, nevermind a work of fiction.
The point I am trying to make is that people think China is a smidgen way from North Korea, when the actual difference is night and day.
If not, then you are incredibly ignorant about China.
It is true, though not to the extremes I think you believe. I would guess that you're getting downvoted because you go from that to "Anything that is published in China, by definition is representative of the opinions of the Party." which is just patently not true (there is plenty of criticism of the CCP in both official published mediums - print, media, etc. - and even more so on blogs, weibo, etc.)
Lastly, your statement can also be applied to many western countries...
