New Federal MP Gladys Liu, the first Chinese-Australian woman to ever sit in the House of Representatives, is facing questions over her links to a secretive Chinese influence network.

The ABC can reveal ties have been discovered between the Liberal member for Chisholm and an organisation linked to Beijing's United Front, which aims to influence politics in foreign countries.

Ms Liu says she only joined the organisation to help promote trade, and has since resigned, but it's yet another controversy for a rookie MP already facing a High Court challenge to her election result.
