A woman from Arunachal Pradesh has alleged severe harassment and illegal detention by Chinese immigration authorities at Shanghai Pudong Airport after they refused to recognise her Indian passport during a transit halt. In detailed posts shared on X, Pema Wang Thongdok described an ordeal that lasted nearly eighteen hours on November 21, when officials insisted her passport was invalid simply because her birthplace was listed as Arunachal Pradesh, which Beijing claims as its territory.
