Pro-democracy boycott of Disney's Mulan builds online via #milkteaalliance

Liu Yifei, who stars as Chinese heroine, has voiced support for Hong Kong police during suppression of protests

Calls to boycott Disney's live-action remake of Mulan have been reignited ahead of its release on Friday, with Thai pro-democracy activists joining those vowing to shun the film.

Controversy over Mulan erupted last year, when its star, Liu Yifei, voiced support for police in Hong Kong, who have been accused of using excessive force against protesters.
