Liberal MP Gladys Liu has refused to criticise China’s actions in the South China Sea, after revelations were made about her connections to Chinese Communist Party organisations.

The Chisholm MP refused to say whether or not China’s actions in the South China Sea were unlawful, despite the findings of an international tribunal in 2016.

Ms Liu has faced a string of allegations over her potential links to the Chinese government, including revelations the Victorian Liberal Party was made to return more than $300,000 from fundraising auctions in 2015 because of security concerns over the successful bidders she had invited.
