Vietnam has pulled the animated film “Abominable” from theatres over a scene featuring a map of the South China Sea showing Beijing’s claims in the flashpoint waterway, cinemas and state media reported Monday.

China has long used its so-called nine-dash line to justify its jurisdiction over most of the resource-rich sea, often to the displeasure of Hanoi, which also claims parts of the waterway.

The U-shaped line appears on a map of the South China Sea in a scene in the film — released in Vietnam as “Everest: The Little Snowman” — which is about a Chinese teenager helping a yeti return to his home.

The movie is a joint production from DreamWorks and China’s Pearl Studio and was released in Vietnam on October 4, but the country’s main cinema franchise CGV said it would no longer show the film after it was notified about the map.

“CGV seriously admit our mistake due to negligence… this is a serious issue,” the South Korean-owned firm said.

All films in communist Vietnam must be approved by censors who screen for gratuitous violence, suggestive sex scenes or politically-sensitive material.

State media earlier quoted the head of the censorship body saying she was sorry for letting the error slip through.

“I will claim responsibility” for the mistake, said Nguyen Thu Ha, the head of Vietnam’s Cinema Department, quoted by Thanh Nien newspaper.

Ha said she would remind her department “to be very vigilant… to be more prudent” in the future.
