A Ban on WeChat and TikTok, a Disconnected World and Two Internets Fang Bing NEW YORK/WASHINGTON - President Trump's new executive orders banning Chinese social media apps TikTok and WeChat marked a significant escalation in the ongoing technology tensions between the U.S. and China, according to analysts. On Aug.6, 2020, Trump declared that TikTok and WeChat posed a threat to national security and invoked the International Emergency Economic Power Act. He prohibited Americans from carrying out any transactions with the parent companies of TikTok and WeChat beyond 45 days -- meaning U.S. companies and individuals will not be able to advertise with the platforms, offer them for download via app stores, or enter into licensing agreements with them. .
