The 1997 epic starring Winslet and Leonardo DiCaprio as star-crossed lovers was re-released worldwide in time for the 100th anniversary of the historic sinking of the luxury liner during its maiden voyage.
A memorable scene in which DiCaprio's poor artist Jack sketches Winslet's society girl Rose naked has been edited in China so Winslet is only seen from the neck up.
"Considering the vivid 3D effects, we fear that viewers may reach out their hands for a touch and thus interrupt other people's viewing," the administration said in a statement. "We've decided to cut off the nudity scenes."
E! News said one Chinese man complained about the alteration in an online film forum.
"I've been waiting almost 15 years, and not for the 3D icebergs," he wrote.
