Disney's 'Mulan' remake is facing fresh boycott calls after it emerged some of the blockbuster's scenes were filmed in China's Xinjiang region, where widespread rights abuses against the region's Muslim population have been widely documented.

The lavish $200m film about a legendary female Chinese warrior was already tangled in political controversy, after star Liu Yifei voiced support for Hong Kong's police as they cracked down on democracy protests last year.

But the latest controversy came to light after the movie began showing on the Disney+ channel last week.

Viewers spotted that Disney included "special thanks" to eight government entities in Xinjiang, including the public security bureau in Turpan, a city in eastern Xinjiang where multiple internment camps have been documented.

Another entity thanked was the Chinese Communist Party's propaganda department in Xinjiang.

The revelation has sparked renewed anger at a time of heightened scrutiny over Hollywood's willingness to bow to authoritarian China.

Rights groups, academics and journalists have exposed a harsh crackdown against Uighur and Kazakh Muslims in Xinjiang, including mass internments, enforced sterilisations, forced labour as well as intense religious and movement restrictions.

Isaac Stone Fish, a senior fellow at the Asia Society, said the film was now "arguably Disney's most problematic movie" since 'Song of the South', a 1946 film about antebellum plantation life that the company has since pulled.

"It's sufficiently astonishing that it bears repeating," he wrote in a Washington Post column.

"Disney has thanked four propaganda departments and a public security bureau in Xinjiang, a region in northwest China that is the site of one of the world's worst human rights abuses happening today."

Badiucao, a dissident Chinese artist living in Melbourne, said he was currently working on a new cartoon portraying Mulan as a guard at one of the internment camps in Xinjiang to satirise Disney's new film.

"It's very problematic and there's no excuse. I mean, it's clear, we have all the evidence showing what is going on in Xinjiang," he told AFP.

Badiucao accused Disney of "double standards" by embracing western social justice movements such as MeToo and Black Lives Matter, while turning a blind eye to China's rights abuses.
