Chinese video-sharing app TikTok has gone to court to challenge a ban imposed by US President Donald Trump.

Axar.az reports citing foreign media.

President Trump's executive order prohibits transactions with TikTok's owner ByteDance from mid-September.

Officials in Washington are concerned that the firm could pass American users' data to the Chinese government, something ByteDance has denied doing.

Tiktok said the Trump administration's move was motivated by politics, not national security.

The popular social media app currently has more than 80 million users in the US.

In its lawsuit, Tiktok said it had taken "extraordinary" steps to safeguard US data in response to Washington's concerns and argued that the order is a misuse of national security law.

The order "is not based on a bona fide national emergency and authorises the prohibition of activities that have not been found to pose 'an unusual and extraordinary threat'," the firm said in the complaint, parts of which were shared on its website ahead of Monday's filing.
