Video sharing service TikTok says it is ending operations in Hong Kong after the enactment of a new national security law. The decision by Chinese-owned TikTok comes after other major internet companies announced they had suspended processing any new requests for user data from Hong Kong’s government. The companies include Facebook, Microsoft, Google, Twitter, Telegram and Zoom. They said the suspensions would remain while they study the new law, which took effect last week. The law reduces Hong Kong’s self-governing autonomy and makes it easier to punish protesters.
