China has emerged as a key architect of global autonomous driving rules after helping develop the world’s first harmonized technical regulation for the field, a milestone expected to reshape how self-driving vehicles are designed, tested and certified across international markets.
As the first global regulation covering the full life cycle of Level 3 and Level 4 automated driving systems, the new rules — known as ADS GTR — were recently adopted by the United Nations Economic Commission for Europe and were jointly led by China, the European Union, the United Kingdom, the United States, Canada and Japan.
The regulation establishes a common set of technical requirements spanning system design, testing, validation, deployment and post-market safety management, replacing fragmented national rules with a unified framework, according to the UNECE.
“This is a landmark achievement in the evolution of the global automotive industry,” said An Tiecheng, chairman of China Automotive Technology and Research Center, which played a key role in the development of the regulation. “It not only establishes a unified benchmark for market access across different jurisdictions, but also lays a solid foundation for the safe and large-scale deployment of autonomous driving technologies worldwide.”
In addition, the new regulation is expected to make it easier for automakers to develop autonomous driving technologies for multiple markets simultaneously, reducing duplicated costs while improving regulatory consistency worldwide.
“Instead of adapting products to different technical requirements in different markets, manufacturers will be able to develop vehicles against a common regulatory framework, significantly improving development efficiency and reducing compliance costs,” he said.
An noted that the new regulation also demonstrates China’s growing influence in international automotive rulemaking.
According to the Ministry of Industry and Information Technology, which coordinated the research efforts in the domestic market, Chinese experts were deeply involved throughout the drafting process for key sections, including the technical rationale, guiding principles and core technical framework of the regulation.
“At CATARC, we submitted dozens of technical proposals on key issues such as dynamic driving tasks and human-machine interaction, in an effort to contribute Chinese expertise to the final regulation,” An said.
He added that the unified regulation is also expected to accelerate the alignment between China’s domestic standards and international rules, as the MIIT recently released for public consultation the country’s first mandatory national standard for Level 3 and Level 4 automated driving systems, which is scheduled to take effect in July 2027.
“China’s forthcoming mandatory national standard on automated driving system safety not only incorporates and localizes the core technical provisions of the just-approved global regulation, but also introduces innovations tailored to China’s industrial realities and regulatory needs,” An said.
He noted that, given China’s complex traffic conditions and diverse driving scenarios, the draft standard sets more detailed technical requirements for both Level 3 and Level 4 automated driving systems. It also strengthens provisions related to user education, operational guidance and driver responsibilities, helping reduce the risks of misuse and overreliance on the technology.
The new national standard will also help lay a solid technical foundation for Chinese autonomous driving products going global.
“By aligning domestic standards with internationally recognized regulations, Chinese automakers will be better positioned to participate in global competition and accelerate the commercialization of automated driving technologies worldwide,” he said.
