President Donald Trump on Thursday August 6, signed executive orders banning social media apps TikTok and WeChat from operating in the US in 45 days if they are not sold by their Chinese-owned parent companies.

The executive orders, one for each app take effect in 45 days.

In the executive order, which declares TikTok a "national emergency", Mr Trump claims the app  "automatically captures vast swaths of information from its users," such as location data and browsing and search histories, which "threatens to allow the Chinese Communist Party access to Americans' personal and proprietary information -- potentially allowing China to track the locations of Federal employees and contractors, build dossiers of personal information for blackmail, and conduct corporate espionage."

The order regarding TikTok prohibits after 45 days "any transaction by any person, or with respect to any property, subject to the jurisdiction of the United States, with ByteDance Ltd.," the Chinese company that owns the social media platform.

For WeChat, which allows its users to transfer funds to each other, the order states it will ban financial transactions with Tencent, a Chinese based company. The order states "any transaction that is related to WeChat by any person, or with respect to any property, subject to the jurisdiction of the United States, with Tencent Holdings Ltd. (a.k.a. Téngxùn Kòngg? Y?uxiàn G?ngs?), Shenzhen, China, or any subsidiary of that entity, as identified by the Secretary of Commerce (Secretary) under section 1(c) of this order

Trump issued the orders under the International Emergency Economic Powers Act, a law that grants the administration sweeping power to bar US firms or citizens from trading or conducting financial transactions with sanctioned parties

On Monday August 3, Trump said he would support the sale of TikTok's US operations to Microsoft and set September 15 as the deadline for TikTok to find a US buyer. 

He also said the deal would have to include a "substantial amount of money" coming to the US Treasury.

In a statement, Microsoft said its CEO, Satya Nadella, spoke to Mr. Trump and "is prepared to continue discussions to explore a purchase of TikTok in the United States".

"[Microsoft is] committed to acquiring TikTok subject to a complete security review and providing proper economic benefits to the United States, including the United States Treasury," the company said.
