The US Commerce Department plans to issue an order Friday that will bar people in the United States from downloading Chinese-owned messaging app WeChat and video-sharing app TikTok starting on September 20, three officials told Reuters.The officials said the ban on new US downloads of TikTok could be still rescinded by President Donald Trump before it takes effect late Sunday as TikTok owner ByteDance races to clinch an agreement over the fate of its US operations.ByteDance has been in talks with Oracle and others to create a new company, TikTok Global, that aims to address US concerns about the security of its users’ data. ByteDance still needs Trump’s approval to stave off a US ban.The Commerce Department order will “deplatform” the two apps in the United States and bar Apple’s app store, Alphabet ‘s Google Play and others from offering the apps on any platform “that can be reached from within the United States,” a senior Commerce official told Reuters.The officials spoke on condition of anonymity because the announcement had not yet been made public.The order will not ban US companies from doing businesses on WeChat outside the United States, which will be welcome news to US firms like Walmart and Starbucks that use WeChat’s embedded ‘mini-app’ programs to facilitate transactions and engage consumers in China.The order will not bar transactions with WeChat-owner Tencent’s other businesses, including its online gaming operations and will not prohibit Apple, Google or others from offering TikTok or WeChat apps anywhere outside the United States.The bans are in response to a pair of executive orders issued by Trump on August 6 that gave the Commerce Department 45 days to determine what transactions to block from the apps he deemed pose a national security threat. That deadline expires on Sunday.Commerce Department officials said they were taking the extraordinary step because of the risks the apps’ data collection poses. China and the companies have denied US user data is collected for spying.In a statement to Reuters, Commerce Secretary Wilbur Ross said “we have taken significant action to combat China’s malicious collection of American citizens’ personal data, while promoting our national values, democratic rules-based norms, and aggressive enforcement of US laws and regulations.”The order is set to be published at 8:45 am EDT (12:45 GMT) on Friday, the officials said.Popular appsThe Trump administration has ramped up efforts to purge “untrusted” Chinese apps from US digital networks and has called TikTok and WeChat “significant threats.”TikTok has 100 million users in the United States and is especially popular among younger Americans.WeChat has had an average of 19 million daily active users in the United States, analytics firms Apptopia said in early August. It is popular among Chinese students, ex-pats and some Americans who have personal or business relationships in China.WeChat is an all-in-one mobile app that combines services similar to Facebook, WhatsApp, Instagram and Venmo. The app is an essential part of daily life for many in China and boasts more than 1 billion users.The Commerce Department will not seek to compel people in the United States to remove the apps or stop using them but will not allow updates or new downloads. “We are aiming at a top corporate level. We’re not going to go out after the individual users,” one Commerce official said.Over time, officials said, the lack of updates will degrade the apps usability.”The expectation is that people will find alternative ways to do these actions,” a senior official said. “We expect the market to act and there will be more secure apps that will fill in these gaps that Americans can trust and that the United States government won’t have to take similar actions against.”Commerce is also barring additional technical transactions with WeChat starting Sunday that will significantly reduce the usability and functionality of the app in the United States.The order bars data hosting within the United States for WeChat, content delivery services and networks that can increase functionality and internet transit or peering services.”What immediately is going to happen is users are going to experience a lag or lack of functionality,” a senior Commerce official said of WeChat users. “It may still be usable but it is not going to be as functional as it was.” There may be sporadic outages as well, the official said.Commerce will bar the same set of technical transactions for TikTok, but that will not take effect until November 12 to give the company additional time to see if ByteDance can reach a deal for its US operations. The official said TikTok US users would not see “a major difference” in the app’s performance until November 12.Commerce will not penalise people who use TikTok or WeChat in the United States.The order does not bar data storage within the United States for WeChat or TikTok.Some Americans may find workarounds. There is nothing that would bar an American from traveling to a foreign country and downloading either app, or potentially using a virtual private network and a desktop client, officials conceded.© Thomson Reuters 2020Is Android One holding back Nokia smartphones in India?
