A ban of the Chinese social-media app TikTok, first floated by the Trump Administration, is now gaining real traction in Washington. Lawmakers of both parties fear the app could be manipulated by Chinese authorities to gain insight into American users and become an effective tool for propaganda against the United States. “Tiktok arrived in Americans’ lives in about 2018 . . . and in some ways it coincided with the same period of collapse in the U.S.-China relationship,” the staff writer Evan Osnos tells David Remnick. “If you’re a member of Congress, you look at TikTok and you say, ‘This is the clearest emblem of my concern about China, and this is something I can talk about and touch.’ ” Remnick also talks with the journalist Chris Stokel-Walker—who has written extensively about TikTok and argued against a ban—regarding the global political backlash against the app. “I think we should be suspicious of all social media, but I don’t think that TikTok is the attack vector that we think it is,” he says. “This is exactly the same as any other platform.”
