US President Donald Trump signed a decree on Friday banning U.S. transactions with the parent companies of the popular video app TikTok and the chat app WeChat within 45 days. This would mean that the two apps in the current form cannot be offered in the US app stores of Google and Apple.

The parent companies of the two apps, ByteDance and Tencent, are Chinese, and Trump fears the app will share information from US users with China.

Trump announced last week that he would ban TikTok. "As for TikTok: there will be a ban in the US. It will apply practically immediately," Trump told reporters at the time. Trump previously announced that he would give TikTok until September 15 to reach a deal with an American concern that would take over the American branch of the app. Microsoft is one of the interested parties.

TikTok has been under attack in the US for a long time. Mike Pompeo, United States Secretary of State, announced last month that he was considering a ban because he said the app is sharing information with the Chinese government.

Pompeo fears that the Chinese government will spy on American citizens in this way and store their private data. There is no evidence that TikTok passes data to China.

80 million active users per month

TikTok is very popular in the United States. According to Reuters news agency, the video app has about 80 million monthly active users there. Last week, TikTok announced it would set up a $ 200 million fund to pay creators in the US for content on the platform.

Chat app WeChat is very popular in China, but the popularity in the United States is not too bad. The app is mainly used by Chinese expats to communicate with family and friends.
