China Releases 7 National Standards for AI Agent Interop

China has released a landmark series of seven national standards for artificial intelligence agent interoperability, marking the country’s first comprehensive framework governing how AI agents discover, communicate, and collaborate with one another. The standards, codified under the GB/Z 185 series, were formally approved by the Standardization Administration of China (SAC) on May 22, 2026, and announced at a press conference held by the State Administration for Market Regulation (SAMR) on June 26, according to Xinhua News.

What the Standards Cover

The GB/Z 185 series establishes a closed-loop standard system that addresses every stage of the AI agent lifecycle: identity identification, capability description, supply-demand discovery, collaborative interaction, and tool invocation. The seven individual standards cover:

1. Overall Architecture (GB/Z 185.1-2026) — the foundational framework
2. Identity Code — unique agent identifiers
3. Identity Management — authentication and authorization
4. Agent Description — capability declaration and discovery
5. Agent Discovery — how agents find each other
6. Agent Interaction — communication protocols
7. Agent Tool Invocation — standardized tool access

As Guangming Daily reported, the series “will effectively solve prominent problems faced by agent interconnection, including non-uniform communication interfaces, difficulty in interconnection, lack of identity management systems, and non-standard collaborative interaction rules.”

Why This Matters

AI agents — autonomous systems capable of perception, memory, decision-making, interaction, and execution — represent the next frontier of artificial intelligence. With the rapid iteration of large language models, AI is accelerating “from the perception and understanding stage into the development stage of generative decision-making and autonomous execution,” as Xinhua noted.

Until now, China’s AI agent industry lacked unified interoperability standards. Each platform used its own communication protocols, identity schemes, and interaction rules, creating fragmentation that raised development costs and hindered cross-platform collaboration. The new standards change that by providing a common language for agents built by different vendors.

According to China News Service, after unifying architecture and interaction rules through the standards, “enterprises can reuse standard components, reduce custom development, and compress product time-to-market; simultaneously establish unified identity authentication and full-process traceability mechanisms.”

The Policy Backdrop

The standards did not emerge in isolation. They are directly linked to the “Implementation Opinions on the Standardized Application and Innovative Development of Intelligent Agents” (《智能体规范应用与创新发展实施意见》), jointly issued on May 8, 2026, by three key government bodies: the Cyberspace Administration of China (CAC), the National Development and Reform Commission (NDRC), and the Ministry of Industry and Information Technology (MIIT), as documented on the CAC website.

This policy framework established four pillars: strengthening the development foundation, maintaining safety standards, driving application-led innovation, and actively cultivating a global ecosystem. The GB/Z 185 series directly implements the “build standards and protocols” pillar, demonstrating China’s coordinated approach where policy and technical standards develop in parallel.

China Mobile’s Role

State-owned enterprise China Mobile Internet Co., Ltd. served as a core participant in drafting all seven standards. According to the China Business Journal, the company participated in top-level framework design, technical攻坚, clause compilation, and scenario validation. It also developed a proprietary IDaaS (Identity as a Service) intelligent agent security interoperability solution, already deployed in products including New Message, 139 Mail, and China Mobile Cloud Drive.

How It Compares Globally

China’s GB/Z 185 series enters a global landscape where the industry has largely converged on a two-protocol architecture: MCP (Model Context Protocol) from Anthropic for agent-to-tool access, and A2A (Agent-to-Agent Protocol) from Google for agent-to-agent coordination — both now under Linux Foundation governance. As TechAhead notes, MCP has achieved 97 million monthly SDK downloads, while A2A has 150+ supporting organizations including AWS, Microsoft, and Salesforce.

China’s approach differs in a fundamental way. Where MCP and A2A are industry-led, open-source protocols developed through vendor-neutral foundations, GB/Z 185 is a government-mandated national standard that takes a more unified, top-down approach — covering both agent-to-agent and agent-to-tool aspects within a single framework. The standards will take effect on February 1, 2027, according to codeofchina.com.

What to Watch For

The key question going forward is international interoperability. Will GB/Z 185-compliant Chinese agents be able to communicate with MCP/A2A-compliant agents from international vendors? The standards do not currently address cross-standard compatibility, raising the possibility of parallel ecosystems.

Another open question is adoption. With over 4,500 companies in China developing and selling AI products, the transition to the new standards will take time. The closed-loop framework is comprehensive, but its real-world effectiveness will depend on implementation quality across China’s diverse AI industry.

What is clear is that China has made a strategic bet: that government-led standardization, executed in parallel with policy development and with state-owned enterprises at the helm, can accelerate AI ecosystem development at national scale. Whether this creates a model for other nations or a walled garden remains to be seen — but the standards themselves represent a significant milestone in the global race to define how AI agents will work together.
