President Trump has issued two sweeping executive orders that would essentially ban the use of the Chinese-owned apps TikTok and WeChat in the United States in 45 days, citing national security reasons. More than 100 million people in the United States have downloaded TikTok, a viral video service. WeChat is a widely used app by Chinese Americans for messaging and other services. China condemned the orders as a “nakedly hegemonic act.” The executive orders come as the Trump administration has been actively working to help Microsoft purchase some of TikTok’s overseas operations.
