1. The Mandate That Changes AI Content Forever
On August 1, 2026, major Chinese platforms — including Tencent, Douyin, Kuaishou, Bilibili, and DeepSeek — published their implementation rules for the《人工智能生成合成内容标识办法》(AI-Generated and Synthetic Content Labeling Measures), a regulation jointly issued by four government departments (Cyberspace Administration of China, Ministry of Industry and Information Technology, Ministry of Public Security, and National Radio and Television Administration). The Measures take effect September 1, 2026 — giving brands and content creators exactly 29 days to comply.
The core requirement is simple but sweeping: all AI-generated text, images, audio, video, and virtual scenes must "show their identity" (亮明身份). Every piece of AI-generated content circulating on Chinese platforms must be labeled as AI-generated, through both visible labels and hidden metadata markers.
This is not a platform policy. This is national law with enforcement mechanisms. The labeling mandate applies across the entire content supply chain — from the AI service provider that generates the content, to the platform that hosts it, to the user who distributes it.
2. The Dual-Label System: Visible + Invisible
The Measures establish a two-layer labeling system designed to work at both the user-visible and machine-readable levels:
Layer 1: Explicit Labels (显式标识)
Content that users can see. AI-generated text, images, audio, video must carry a visible label indicating AI origin. For video and audio, this typically means a persistent on-screen marker or watermark; for text and images, a tag or badge near the content.
Layer 2: Implicit Labels (隐式标识)
Machine-readable metadata embedded in the content file itself. AI service providers are required to write implicit identifiers into the metadata of AI-generated content at the point of generation. This metadata persists even after downloads, screenshots, and re-uploads, providing a technical basis for content provenance and traceability.
The system is designed to be tamper-proof: the Measures explicitly prohibit deleting, altering, forging, or concealing AI labels. Platforms are required to verify content metadata when content is uploaded, add risk warnings to unlabeled or suspected AI content, and take action against content that attempts to evade labeling.
For platforms, this means a new enforcement layer: Douyin's implementation includes an AI content metadata read/write function that detects and writes metadata for content provenance; Tencent's rules require both explicit and implicit labeling with platform-side verification.
3. Platform Implementation Rules: The September 1 Front Line
Each platform has published its own detailed implementation, revealing how the mandate will operate in practice:
| Platform | Implementation Highlights |
|---|---|
| Douyin | AI content labeling function + metadata read/write for provenance. Creators who don't label will get platform-assisted labeling |
| Tencent | Explicit + implicit dual labels; platform verifies content identity; risk prompts for suspected AI content |
| Kuaishou | AI labeling rules aligned with the national mandate |
| Bilibili | AI content labels implemented per the Measures |
| DeepSeek | As an AI service provider, must write implicit labels into generated content metadata |
Douyin's approach is particularly notable: if a creator fails to label AI content, the platform will detect suspected AIGC use via technical means and add a "suspected AI-generated content, please verify carefully" label. The risk of mislabeling — being flagged as AI when you're human — creates a new compliance consideration for brands producing large volumes of content.
4. What This Means for Brand Marketing
For TMG's audience of cross-border marketers operating in China, the AI content labeling mandate carries four immediate implications:
Implication 1: AI content production pipelines must embed labeling as a standard step.
From September 1, every AI-generated asset in a brand's content pipeline — product images, marketing copy, video spots, audio ads, virtual influencers — must carry explicit and implicit labels. This is not optional metadata; it is a legal requirement. Brands using AI service providers (DeepSeek, Doubao, Qwen, etc.) should verify that their provider writes implicit labels into output metadata, and should audit their content management systems for labeling support.
Implication 2: The compliance cost of AI content has increased — and so has the risk of mislabeling.
Platforms now actively detect suspected AI content. Human-created content that happens to look AI-generated may receive false-positive "suspected AI" labels. Brands should understand each platform's detection and labeling rules, maintain content provenance records (original files, generation logs, human editing trails) to dispute false labels, and design AI content with obvious human review and approval traces.
Implication 3: AI-generated advertising and influencer content faces new scrutiny.
The labeling mandate applies to all AI-generated content — including commercial content. AI-generated influencer posts, AI-written ad copy, AI-produced video ads, and virtual brand ambassadors must all be labeled. This creates a transparency requirement that may affect consumer trust dynamics: labeled AI content may face different engagement patterns than unlabeled content.
Implication 4: The 'GEO for AI content' playbook must now include label compliance.
The July 24 WeChat AI Search citation analysis and the July 31 AI video production analysis established that AI-generated brand content must be optimized for AI consumption. The labeling mandate adds a compliance dimension: AI-generated content that is properly labeled is the only kind that can legally circulate. Brands should treat label compliance as a baseline requirement for any AI content strategy.
