China’s advertising regulator is finishing a six-month enforcement sweep that every foreign brand running paid campaigns in the country should know about.
What Happened
On March 13, 2026, the State Administration for Market Regulation (SAMR, ????????) launched a national six-month enforcement campaign targeting advertising cautionary statements and disclosure language. The campaign runs through September 2026.
Four categories of violations are in scope: missing mandatory disclaimer statements, superlative claims (“best,” “number one,” “leading”), unverifiable third-party endorsements, and gaps in platform-level content supervision. Fines apply at two levels: the advertiser and the platform that distributed the ad. The DLA Piper briefing published on the same date covers the regulatory text in detail: China Launches Six-Month Enforcement Campaign Targeting Advertising Cautionary Statements.
Why Now, and What It Changes
China’s Advertising Law of 2015 already banned absolute superlatives. Article 9 explicitly prohibits terms like ?? (best), ?? (number one), and ??? (most advanced) in commercial advertising. The problem was not the law. It was enforcement: until 2026, SAMR acted mostly on consumer complaints, which meant brands that avoided public controversy were rarely touched.
Three factors shifted the calculus.
First, consumer complaints about misleading health and quality claims surged after COVID-19. Trust in brand-generated “scientific” copy fell sharply, and regulators came under political pressure to act before another wave of consumer backlash.
Second, the major platforms have grown too large to ignore. Douyin, WeChat, and Baidu now collectively deliver hundreds of billions of ad impressions per year. SAMR wants these platforms to take editorial responsibility before content runs, not after a complaint lands. The campaign explicitly targets platform-level supervision gaps, meaning a brand can be fined and the platform can be fined for the same ad.
Third, the timing fits a broader pattern of tightening platform accountability that started with the internet regulation wave of 2021. Advertising compliance is the next layer.
What changes in practice: Douyin and Baidu in particular have updated their pre-submission review systems to flag superlative language automatically. Ads containing ??, ??, ???? (globally leading), ???? (industry first), or equivalent English terms in Chinese-targeted campaigns are now stopped at review, not just flagged after publication. Brands with campaigns already live are exposed to retroactive review.
The highest-risk category is foreign brands whose Chinese copy was translated directly from English marketing materials. Phrases like “world’s leading,” “globally recognized,” “best-in-class,” and “industry pioneer” are standard in English B2B and consumer copy. Drop them into a Douyin or WeChat ad in Chinese and you have a textbook Article 9 violation.
Who Is Directly Exposed
Any foreign brand currently running paid media in China with copy that includes superlative language is exposed. This is especially common in three situations.
First, brands that localized their global taglines phonetically or literally. “The world’s best [product]” becomes ???? [??], which is a direct violation.
Second, brands running B2B lead generation on Baidu or LinkedIn China with copy borrowed from English white papers or product pages. Technical claims like “industry-leading throughput” or “the most advanced solution” rarely survive translation into compliant Chinese.
Third, brands in health, beauty, and food categories that use clinical-sounding claims without attached study citations. The cautionary statement requirement specifically targets this: if a claim references efficacy or safety, the legal basis or study must appear in the ad or in an immediately accessible disclosure.
The campaign ends in September 2026, but enforcement actions triggered during the campaign period can continue afterward. Brands should not wait for SAMR to close the campaign before reviewing their copy.
What to Do Before Your Next Campaign Launch
The fix is an advertising copy audit focused on four points.
First, identify every superlative in your live and queued Chinese copy. Replace them with specific, verifiable claims. “97% customer satisfaction across 14 markets” is compliant. “The best in its category” is not. Specificity is the safeguard.
Second, check every third-party endorsement. If a quote from a research firm or industry body appears in your ad, the source, date, and methodology must be traceable. SAMR can require brands to produce the underlying documentation on request.
Third, review mandatory disclaimer fields. Financial products, health supplements, insurance, and real estate advertising in China have specific cautionary statement requirements. Missing or truncated disclaimers trigger automatic violations regardless of whether the claim itself is accurate.
Fourth, confirm that your platform accounts are set to submit ads for pre-review rather than direct publication. Most major platforms now default to pre-review for new advertisers, but accounts created before 2024 may still have legacy settings.
A professional audit of your Chinese advertising copy, combined with a line-by-line review against the 2015 Advertising Law and the SAMR 2026 campaign criteria, takes two to four weeks depending on the volume of active campaigns. Given that the campaign closes at the end of September, that review is already overdue for brands that have not started.

One Question Worth Debating
Does stricter advertising enforcement in China benefit foreign brands over the long term, or does it add enough compliance friction to favor local competitors who already know the rules and have relationships with platform review teams? The answer probably depends on how well your China team is set up, and that is not a consensus view among marketers in the region.
