BBC said, TikTok is threatening legal action against the US after their president Donald Trump act on firms to stop doing business with the Chinese app within 45 days.
The company replied that they were “shocked” by an executive order from the US President disclosing the ban.
TikTok said it would “pursue all remedies available” to “ensure the rule of law is not discarded”.
According to BBC, Mr Trump issued a familiar act against China’s WeChat in a major escalation in Washington’s stand-off with Beijing.
WeChat’s owner, Tencent, said: “We are reviewing the executive order to get a full understanding.”
The president has already threatened to ban TikTok in the US, citing national security concerns, and the company is now in talks to sell its American business to Microsoft. They have until 15 September to reach a deal – a deadline set by Mr Trump which is a period of 45 days.
The Trump administration claims that the Chinese government has access to user information gathered by TikTok, which the company has denied.
