Chinese censors have refused to allow the film to be screened because of its "violent and supernatural content".
Reports suggest the Film Bureau, which is government controlled, didn't approve of the movie's portrayal of souls of the dead or the ferocious "octopus-faced" character, Davy Jones, played by actor Bill Nighy.
Although China does not have a film rating system, censors usually reject scenes of sex and violence, passing only 20 foreign films a year.
Meanwhile, the movie has broken box office records on its first weekend of release.
In the US, the pirate sequel took a record $132 million in just three days - beating the previous high of $115 million set by 'Spider-Man' in May 2002.
On Friday (07.07.06) alone, 'Pirates of the Caribbean: Dead Man's Chest' took $55.5 million - beating previous record holder 'Star Wars Episode III: Revenge of the Sith' which took $50 million on its first day of release last year.
