China announces 'compulsory measures' against Australian writer despite criticism

China's foreign ministry said Friday it has taken "compulsory measures" against Chinese-born Australian writer Yang Hengjun, who has been in detention since January on suspicion of action that endangers state security.

Australia said Friday that it was "deeply disappointed" upon receiving notification that Yang had been transferred to criminal detention. In response, China called on Australia to stop issuing irresponsible remarks.

Foreign Ministry spokesman Geng Shuang made the comments at a press briefing.
