People in the United States will be banned from downloading Tiktok from this Sunday.

The U.S. Department of Commerce says Americans will no longer receive the popular video-sharing app from September 20.

The bans will also cover the messaging app WeChat.

President Donald Trump may lift the ban before Sunday evening if an agreement is reached between Chinese owners of TickTock byteDance and US technology giant Oracle.

The two companies are in talks to create a new agency called Tiktok Global, which aims to address concerns about data protection for White House users.

TickTock has 100 million users in the United States.

A statement from the department said: “The Chinese Communist Party (CCP) has demonstrated the ways and purposes of using these apps to threaten national security, foreign policy and the US economy.

“The bans announced today protect users in the United States from being excluded from accessing these applications and significantly reducing their effectiveness when added.”

It went on to say: “The threats posed by WeChat and TickTock are not the same, they are the same. Each network collects detailed information from users, including activity, location data, and browsing and search history.

“Everyone is an active participant in China’s civilian-military engagement and subject to mandatory cooperation with the CCP’s intelligence services.

“The use of WeChat and TickTock as a result of this combination creates an unacceptable risk to our national security.”

Tiktok said it would never share user information with Chinese authorities.

Bytens and Oracle have submitted a proposal for a deal that would make Tiktok a separate U.S. entity with the American Board.

There will also be a security committee – headed by an official security clearance.

Microsoft had previously been in the running to accept the app, but their offer was turned down on September 13th.

Any deal would require the approval of both Washington and Beijing.
