Timeline: Journalists caught in Australia-China diplomatic tussle

SYDNEY (Reuters) - Australia and China are engaged in a dispute that has entangled journalists in both countries.

Following are key dates:

June 26 - Australian Federal Police search the Sydney home and office of New South Wales Labor party politician Shaoquett Moselmane, and the home and business of his staff member John Zhang, in a foreign interference investigation centred on Zhang.

Moselmane says he is not a suspect.

- The Australian Secret Intelligence Organisation (ASIO) questions at least one Chinese journalist in Australia in connection to the same investigation, according to a Sept 9 report in The Sydney Morning Herald citing an unnamed Australian security source.

Aug 3 - John Zhang makes application to overturn Australia’s foreign interference legislation in the High Court. Court documents state he is being investigated by police under the law introduced in 2018.

He is alleged by AFP to have acted on behalf of the Chinese state in a private social media chat group with Moselmane and encouraged the politician to advocate for Chinese state interests. No charges have been laid. Zhang’s lawyers did not respond to Reuters calls for comment on the allegation and he is seeking to have the search warrants overturned in the High Court.

Sept 3 - Smith and Birtles are offered consular protection in Australian diplomatic posts as negotiations take place between Australian and Chinese officials.
