Cheng Lei: Australian journalist arrested on China spying charges

Australian journalist Cheng Lei, after months of detention in China, has been formally arrested on charges of supplying state secrets overseas.

Prior to her detention, the Chinese-born Australian had been a TV presenter for Chinese state media outlet CGTN.

Chinese authorities confirmed her arrest on Monday, adding that her legal rights would be guaranteed.

Ms Cheng was detained in August and charged last Friday, Australian officials had earlier said.

At a press briefing on Monday, Chinese ministry spokesman Wang Wenbin said he hoped Australia would "not interfere with China's handling of this case", according to news agency Reuters.

Canberra has repeatedly raised concerns with Beijing over Ms Cheng's detention.

"We expect basic standards of justice, procedural fairness and humane treatment to be met, in accordance with international norms," said Australia's foreign affairs minister, Marise Payne.

"Our thoughts are with Ms Cheng and her family during this difficult period."
