Chinese-Australian business developer Chau Chak Wing has hit back after a Labor senator tied him to a failed foreign interference plot, calling the comments "baseless and reckless".
Labor senator Kimberly Kitching used parliamentary privilege to ask the head of Australia's counter espionage agency whether Dr Chau was the man referred to in his annual threat assessment speech.
The case involved an unnamed wealthy person - described as the "puppeteer" - who had "direct and deep connections with a foreign government and its intelligence agencies", ASIO Director-General Mike Burgess said.
