Chinese-owned messaging app WeChat has been accused of showing contempt for federal parliament by defying repeated requests to appear before a parliamentary inquiry that is weighing whether to recommend banning the app from use in Australia because of foreign interference concerns.

Executives from social media giants TikTok, Google, Twitter and LinkedIn have all agreed to appear at the final public hearings of the Senate select committee on foreign interference through social media in Parliament House on Tuesday.

About 1 million people in Australia – including almost half the Chinese diaspora – are believed to use WeChat, which has been described as “China’s app for everything”.
