World War II movie dominates mainland box office, raising fears of further decline in ‘already negative mutual perceptions in both countries’

For a movie about a particularly dark chapter of China’s history, 731 has been doing exceptional business.

It has topped the Chinese box office, taking more than 1.1 billion yuan (US$154.6 million) in revenue by Sunday, according to Lighthouse Professional Edition, a Chinese box office website.

The film’s release is the latest in a series of events to mark the 80th anniversary of Japan’s defeat in the war and comes as each country’s perceptions of the other has declined – a situation some say will be exacerbated by the movie.

The film follows the story of a group of people imprisoned who try to escape from the facility.
