US distances itself from Trump attempts to ban WeChat

The Commerce Department is reviewing recent actions, such as the rules undermining TikTok and WeChat, to ensure that efforts by the Trump administration to ban them based on claimed national-security threats were justified, according to a Thursday government filing in a suit by WeChat users challenging the ban. 

Courts have blocked Trump's attempted ban of WeChat from going into effect, saying it would affect affect the First Amendment rights of users. 

WeChat is a messaging app with other features like social media and payments that is dominant in China, where many American social media and messaging apps are banned. It is also popular with many Chinese speakers in the U.S., with millions of users, since it allows them to connect with friends, family and business contacts in China. It's owned by Chinese tech giant Tencent. 

Within China, WeChat is censored and expected to adhere to content restrictions set by authorities. The Citizen Lab internet watchdog group, based in Toronto, has said WeChat monitors files and images shared abroad to aid its censorship in China. 

The Trump administration targeted WeChat and TikTok because of their Chinese ownership, saying that U.S. user data could be shared with the Chinese government. TikTok has denied it does or would do this. Tencent has said it incorporates the highest standards of user privacy and data security. 

The attempted bans were part of the administration's ratcheting up of tensions with China, which included a trade war, blocking mergers involving Chinese companies and stifling the business of Huawei, a maker of phones and telecom equipment.
