Scott Morrison's Chinese social media account blocked

Prime Minister Scott Morrison's profile on a Chinese social media network has been blocked and rebranded with pro-Communist Party messaging.

Mr Morrison's WeChat account, which has 76,000 followers, is the federal government's main tool for communicating with Chinese Australians.

But the account has been blocked and renamed 'Australian Chinese new life' and its description changed to "provide life information for overseas Chinese in Australia".

The Prime Minister's Office has been trying to contact the the Chinese-owned app to regain access to the account but there has been no response.

WeChat is regularly monitored and censored by the ruling Chinese Communist Party.

The incident prompted calls today for politicians to boycott the app.

Senator James Paterson, Chair of the Joint Parliamentary Committee on Intelligence, told 2GB radio it's "very concerning".

"What the Chinese government has done is effectively foreign interference in our democracy and in an election year.

"There is no reason for Australian politicians to be on there anymore if the Chinese government is going to set the terms of the debate."

The WeChat account of Opposition Leader Anthony Albanese remains unaffected.
