Australian authorities are still trying to establish whether Wang Liqiang is a Chinese spy or a shyster.
Wang is seeking political asylum in Australia after approaching ASIO with information about Chinese intelligence operations.
But China has released video purporting to show Wang pleading guilty to fraud charges in 2016.
Foreign Minister Marise Payne gave a careful response when asked what she made of the footage.
"These are serious allegations and they should be dealt with seriously," Senator Payne told ABC radio on Friday.
The minister quickly pivoted to the broader threat of foreign interference in Australian politics.
"We made changes to our laws to address foreign interference no matter where it comes from, no matter who is responsible," she said.
"It's important that Australia has these laws in place and that we enforce them."
Liberal MP Andrew Hastie, who chairs parliament's intelligence and security committee, confirmed he put the self-proclaimed spy in touch with ASIO.
The former soldier was at a conference in Hawaii when he was contacted by an intermediary of Mr Wang's.
He claimed to have information on how Chinese intelligence officers funded operations on Hong Kong, Taiwan and Australia.
"My immediate reaction was to put it back through official channels, to hand it off to the intelligence services," Mr Hastie told The Australian.
