Vietnam, a one-party communist state with low tolerance for public criticism or dissent that has jailed scores of journalists and bloggers, is moving to tighten content rules for social media. Amended laws will require platforms like Facebook and TikTok to remove content and services deemed illegal within 24 hours, block illegal livestreams within three hours of notice, and immediately remove content that endangers national security–or risk being banned in the country of 98 million people.
