The children of detained Australian writer Yang Hengjun have pleaded with PM Anthony Albanese to up the pressure on China to release their dad. Dr Yang has been held without charge for 4 years, and he’s said to be in a bad way because of a kidney cyst that isn’t being treated. In a letter to the PM, his sons say consular officials who were allowed to visit Yang last week found him bedridden, and they’re worried he might die from “calculated medical neglect”. Albanese has promised to raise Yang’s case with Chinese leaders – and he’s also been asked by Aussie Uighur, Tibetan, and Hong Kong communities to raise China’s “crimes against humanity” during his visit to Beijing starting on Saturday. Dr Yang’s sons say they were inspired by Australian journalist Cheng Lei’s release and hope the PM can “achieve a second miracle by saving our father”.
