China Warns Australia Not to Interfere in Case of Writer Suspected of Spying Phil Mercer SYDNEY - Chinese authorities have warned Australia not to interfere in the case of a Chinese-Australian writer who has been formally arrested in China on suspicion of spying. Yang Hengjun, who was born in China but is an Australian citizen, has been held in Beijing since January. Australia has become increasingly critical of China's treatment of him in recent months. Yang Hengjun has been under investigation for allegedly harming China's national security, but Australian officials have been told he is now suspected of espionage. The former Chinese diplomat has been detained in Beijing without access to family or lawyers since January. In a strongly worded statement, the Australian government says the writer is being held in "harsh conditions" and it has "serious concerns for his welfare." Foreign minister Marise Payne said that if the Sydney-based academic was "being held for his political beliefs, he should be released."
