Ten Yangtze River Delta cities form data annotation alliance in Nanjing
In short
A national data annotation pilot alliance of Jiangsu and Anhui cities was set up in Nanjing, Jiangsu, on 20 October, the 2026 Physical AI and World Model Conference was told. Ten Yangtze River Delta cities, including Nanjing and Wuhu in Anhui, will develop the data annotation industry together and have set up a joint innovation centre.

A national data annotation pilot alliance of Jiangsu and Anhui cities has been established in Nanjing, Jiangsu. The announcement was made at the 2026 Physical AI and World Model Conference, held on 20 October. Ten Yangtze River Delta cities will work together to develop the data annotation industry, which the reports describe as providing important support for regional artificial intelligence innovation. [ 1 , 2 , 3 , 4 ]
The reports, which all trace to CCTV News, explain that data annotation is the base of the AI industry. In plain terms, it means classifying and labelling images, text and scenes so that AI can read, recognise and learn the patterns of real scenarios, speeding up the refinement and use of large models. [ 1 , 2 , 3 , 4 ]
Nanjing in Jiangsu and Wuhu in Anhui are among the ten cities, which have jointly set up a data annotation joint innovation centre. The coverage says the centre will address long-standing problems in the sector: scattered industry resources, differing standards and insufficient regional coordination. [ 1 , 2 , 3 , 4 ]
Jiemian also quoted Cao Haibin (曹海斌), head of the digital infrastructure and digital technology division at the Nanjing Data Bureau. He said the ten cities will cooperate in five areas, including building an industry public service platform and mutual recognition of data standards. The aim, he said, is to bring together scenes, data, computing power and talent spread across different places, and to offer a Jiangsu-Anhui approach to data annotation in industrial manufacturing and other fields that can be copied and extended nationwide. [ 4 ]
Jiemian added that the conference, which opened on 20 October, focuses on the full chain from data supply and model training to application scenarios and industrial use. It will discuss how a standardised supply of quality basic data can strengthen the base for AI development and better serve the real economy. [ 4 ]
Why it matters
The outlets, all relaying CCTV News, present the alliance as a way to address scattered industry resources, differing standards and weak regional coordination in data annotation. The documents give no figures or timetable, so its practical effect is not yet shown.

Confirmed by several sources
- Nothing is confirmed by two independent outlets yet.
Still unclear
- Which cities besides Nanjing and Wuhu belong to the alliance. The documents name only Nanjing and Wuhu and refer to the rest as ten Yangtze River Delta cities.
- What the five areas of cooperation are in full. Only Jiemian gives details, naming industry public service platform construction and mutual recognition of data standards; the other three are not listed.
- Whether the centre will resolve the problems of scattered resources, differing standards and weak coordination. This is stated as an expected outcome in the reports, which all trace to CCTV News; no results or timetable are given.
- The alliance was founded in Nanjing, bringing together ten Yangtze River Delta cities to develop the data annotation industry. Reported by a single source so far
- The cities set up a data annotation joint innovation centre. Reported by a single source so far
