China says detained Australian Yang in good condition, not tortured

China's foreign ministry said on Monday that a Chinese-born Australian writer detained by Beijing for almost a year is in good condition and has not been tortured, rejecting criticism by the Australian government about his treatment.

Chinese foreign ministry spokesman Hua Chunying made the remarks during a daily news briefing in Beijing.

Australian Foreign Minister Marise Payne said Australian consular officials who recently visited Yang Hengjun had reported "unacceptable" conditions, including isolation and daily interrogations, sometimes while he was shackled.
