Per The Telegraph, censors frowned upon a couple of scenes where some aliens disguise themselves as employees at a Chinese restaurant in New York City's Chinatown, saying it cast those of Chinese ancestry in a bad light.

What's more, offense was taken when Smith's Agent J erases the memories of a group of Chinese bystanders.

"This could have been a hint on the use of internet censorship to maintain social stability," commented China's Southern Daily newspaper (via The Telegraph).

So, they may have censored the scene because it may or may not have alluded to already-existing censorship? OK, then.
