WASHINGTON (REUTERS) - A top White House adviser said on Thursday (July 16) that he expects TikTok to separate from its Chinese owner and operate as an American company amid growing US concerns about the security of the data handled by the short video app.

White House economic adviser Larry Kudlow told reporters a move by TikTok to leave Beijing ByteDance Technology, would be a better option than a ban on the app, which was threatened by State Department Secretary Mike Pompeo earlier this month.

"We haven't made final decisions but... I think TikTok is going to pull out of the holding company which is China-run and operate as an independent American company," Kudlow said.

Kudlow did not specify whether TikTok's ownership would change under the proposed structure.

He declined to comment when asked if US companies could acquire TikTok.

When asked about Kudlow's remarks, a TikTok spokesman said the company would not "engage with speculation in the market," and referred to a statement last week noting that ByteDance was "evaluating changes to the corporate structure of its TikTok business" and was fully committed to protecting users privacy and security.

Kudlow's comments come as TikTok finds itself increasingly in the crosshairs of the Trump administration, with US-China relations strained by the coronavirus pandemic and Beijing's move to curb freedoms in Hong Kong.

President Donald Trump's chief of staff said on Wednesday that the administration is studying the national security risks of social media applications including TikTok and WeChat, with action to address the issue expected in the coming weeks, a White House official.

On Wednesday, the New York Times reported the administration was weighing action against Chinese social media services like TikTok under the International Emergency Economic Powers Act, which gives the president broad powers to penalise companies in response to extraordinary threats, citing people familiar with the matter.
