It was a typical Trump: on Friday, the US President threatened to switch off the American edition of the Chinese video platform TikTok.

Downloads of the app should be blocked from Sunday onwards.

But a few hours before the deadline that Trump had set, he changed his mind.

The deal between TikTok's Chinese owner ByteDance, the US software company Oracle and the retail giant Walmart has a "blessing", announced Trump on Twitter.

ByteDance is to outsource the global business with the app to an independent company called TikTok Global. Almart and Oracle will jointly receive 20 percent of the shares.

The companies want to negotiate the details of the agreement by the end of the week.

Oracle is supposed to make sure that the private data of the users does not flow to the Chinese government.

That was one of the demands of the US government.

Trump also demanded that TikTok be given an American owner and that its algorithm should be handed over to American hands.

The deal that Trump is now approving does not fulfill either of the last two points.

ByteDance remains a co-owner.

To get an American majority stake, you have to add up the shares of Oracle and Walmart in TikTok and add the investment funds Sequoia and General Atlantic, which are already involved via ByteDance.

The question also remains open of whether the deal will prevent China from using TikTok as a Trojan horse, tapping data from 100 million US users and censoring content.

This should prevent the algorithm from being sold, but the Chinese government passed a law to prevent such technology from being sold overseas.

It is unclear whether the deal really protects data

If China approves the new deal, TikTok would have to inform Oracle in the future if it changes the logic according to which content is proposed to users.

In addition, Oracle should get access to the source code of the app in order to be able to check whether ByteDance installs so-called back doors.

But how the Americans should recognize manipulation and possible influence if the algorithm remains under Chinese control is one of the open questions of forced marriage.

Basically, with this agreement, Trump only gets what ByteDance had promised him months ago.

The company asserted that data had never flowed to China and that it will not in the future. ByteDance also promised to relocate TikTok's headquarters to the United States and create thousands of new jobs there.

After all, Trump could do a friend a favor by giving Oracle the job.

Its founder and supervisory board chairman Larry Ellison is one of the few tech entrepreneurs from Silicon Valley who openly support Trump.

It wasn't until February that he made his house available for an event to raise funds for Trump's election campaign.

There is calculation behind Trump's anti-China course

The president has already prevented the Chinese telecommunications supplier Huawei from selling its infrastructure for the 5G cellular standard in the USA.

But the crackdown on TikTok is unprecedented.

The video platform primarily appeals to teenagers and young adults.

The proportion of Trump fans is likely to be lower than the rest of the population.

TikTok users called for creative protest against the US president several times.

With the tough course against a Chinese company, Trump wants to build on the successful 2016 election campaign.

At that time, it scored particularly well with people in the Rust Belt.

There many believe that the migration of jobs abroad is to blame for the fact that they have lost their jobs and that the former industrial regions are being economically left behind.

Trump is apparently counting on the fact that he can mobilize these voters again.

As expected, the Chinese reacted indignantly.

TikTok has been hunted and cornered by the US government, Wang Wenbin, spokesman for the Chinese Foreign Office, said at a press conference last week.

Trump's actions show the real intentions of the Americans and expose the "ugly face of economic tyrannization".

A new era of protectionism is looming

However, the Chinese government also regularly excludes foreign companies.

They will be forced to team up with Chinese partners, disclosing their technology.

The fact that Trump, as head of state of the nation, which otherwise pretends to be a pioneer of the free market economy, is now at this level, makes matters even worse.

The US President has long since started a new wave of protectionism, which the pandemic only intensifies.

Trump is no longer alone in the West either: The French government is trying to prevent the takeover of the luxury group LVMH by the New York jeweler Tiffany, which was signed in November 2019.

LVMH, owner of brands such as Dom Perignon and Louis Vuitton, wants to break the merger with reference to a letter from the Paris government.

French Foreign Minister Jean-Yves Le Drian is pushing for a postponement because Trump is threatening to impose tariffs on French exports - because France, for its part, wants to introduce a digital tax that would primarily affect US technology companies.

The more governments intervene in the economy in this way, the more international trade is in danger.

That is also risky for Germany.

The German economy is still dependent on exports, which in turn depend on freely accessible markets.

At first glance, the dispute over luxury handbags and the struggle for the US version of a video platform on which teenagers perform dance routines may have little to do with our everyday lives. In fact, they represent a development that threatens the economy and prosperity in Germany as well.
