Australia evacuates journalists from China amid 'national security' probe

Two Australian foreign correspondents were rushed out of China for their safety with the help of Australian consular officials after being questioned by China's Ministry of State Security.

China correspondents for the Australian Broadcasting Corporation (ABC) and the Australian Financial Review (AFR) sought shelter in Australia's embassy in Beijing and consulate in Shanghai as diplomats negotiated with Chinese officials to allow them to leave the country, the ABC and the AFR reported.

The two journalists - the ABC's Bill Birtles and the AFR's Michael Smith - had been banned from leaving China until they answered questions about detained Australian citizen and television anchor Cheng Lei, the media companies reported.

Both journalists were told they were "persons of interest" in an investigation into Cheng, a high-profile business anchor on Chinese state television, who was detained by authorities in August, the AFR report said.

Arriving at Sydney airport on Tuesday morning, Smith told reporters it was "such a relief to be home".

Birtles told reporters at the airport "this was a whirlwind and it was not a particularly good experience".

It was "deeply disappointing to leave China under such abrupt circumstances. It's been a big part of my life & the past week was surreal," Birtles wrote on Twitter.

Public broadcaster the ABC reported that Australian diplomats warned Birtles last week that he should leave China.

The correspondent was having farewell drinks with friends and colleagues when seven police officers arrived at his apartment at midnight on September 2 and told him not to leave the country until he could answer questions about a "national security case".

It was then he called the Australian embassy for assistance and took refuge in the diplomatic compound.

Australian Foreign Minister Marise Payne confirmed in a statement that the embassy in Beijing and consulate-general in Shanghai had "engaged with Chinese Government authorities to ensure their wellbeing and return to Australia".

The ABC said it brought Birtles back to Australia following advice from the Australian government.

The departure of the two journalists meant Australian media organisations had no correspondent in China for the first time since the 1970s, said Penny Wong, foreign affairs spokeswoman for the opposition Labor party. Wong said this was "deeply regrettable".

Australia has a tense diplomatic relationship with China, which worsened this year after Beijing threatened trade reprisals and said it was angered by Australia's call for an international inquiry into the source of the coronavirus pandemic.

The Australian government was continuing to provide consular support to Cheng, Payne said.
