Seven documents, five dimensions, 100+ participating companies. China has placed its first piece on the AI agent protocol standardization chessboard, ahead of Europe and the US.

China's State Administration for Market Regulation and Standardization Administration formally approved the GB/Z 185-2026 "Artificial Intelligence — Agent Interconnection" series of seven national standardization guidance technical documents. This is China's first national standards framework covering the full agent lifecycle, marking China's transition from market application leadership to standard-setting leadership in this critical arena.

Five Dimensions Covering the Full Agent Stack

The GB/Z 185 series has a remarkably comprehensive architecture, covering the full chain from an AI agent's "birth" to its "collaboration."

The standards revolve around five core dimensions: identity, capability description, supply-demand discovery, collaborative interaction, and tool invocation. Identity solves the "who am I" question by giving each agent a unique identifier. Capability description solves "what can I do" by defining structured representations of agent abilities. Discovery solves "who can do this for me" through agent service registration and lookup mechanisms. Collaboration solves "how do we work together" by defining inter-agent communication protocols and coordination patterns. Tool invocation solves "how do I take action" by unifying interfaces for agents calling external tools and resources.

These five dimensions cover essentially every aspect of agent interconnection. Compared to the evolving international protocol ecosystem — MCP handling tool invocation, A2A (Agent-to-Agent) handling collaboration, ACP handling in-IDE agent integration — China's national standard is a higher-level, more comprehensive framework that seeks to bring various protocols under a unified standards umbrella.

The engineering implementation is AIP (Agent Interconnection Protocol), an open-source project led by Beijing University of Posts and Telecommunications and the China Electronics Standardization Institute. AIP v2.1.0 just shipped, with 100+ companies including Huawei and 360 already participating. An open standards ecosystem led by academia with broad industry participation is taking shape.

Standard-Setting Power Is Industry Clout

Why does this national standard matter? Because as the AI industry enters the agent era, whoever sets the standards holds the industry's microphone.

Looking at internet history, TCP/IP defined network-layer communication rules and HTTP defined web-layer interaction standards — whoever made the protocol controlled the ecosystem. In the AI agent era, no unified interconnection standard exists globally: in the US, MCP is led by OpenAI, A2A by Google, ACP by JetBrains and community efforts — each doing its own thing. The EU remains focused on implementing the AI Act, moving slowly on technical standards.

China launching a unified national standard in this window sends at least three signals. First, China's agent application market has reached the stage where standards are necessary — when thousands of agents are running in the market, interconnection and interoperability become essential, and standards are a sign of industry maturity. Second, China is trying to get a head start on agent interconnection standards — national standards first, then pushing for international adoption, following the same playbook as 5G standard-setting. Third, regulation and development move in parallel — these standards aren't just technical specifications; they provide a technical foundation for future agent governance, security auditing, and liability determination.

Of course, guidance technical documents (GB/Z) don't carry the same legal force as mandatory national standards (GB) — GB/Z is recommended, not required. But in China's industrial environment, recommended national standards often become de facto standards for government procurement, SOE bidding, and industry entry, giving them practical clout.

The agent protocol wars have only just begun. MCP, A2A, ACP, AIP — whichever becomes the "HTTP" of the agent era will define the next decade's AI infrastructure landscape. China has played its card.

See you tomorrow.
