Yang Hengjun was taken into custody upon arriving in southern China's Guangzhou from
New York in January with his wife, Yuan Xiaoliang, and his 14-year-old stepdaughter.
Foreign Minister Marise Payne said she was “very concerned” by reports from
Australian officials following their latest monthly consular visit to Yang, who remains in criminal detention.
“His circumstances of detention include increased isolation from the outside world, with restrictions on his communications with family and friends and the resumption of daily interrogation, including while shackled,” Payne said in a statement.
