Wuzhen town in Jiaxing, East China's Zhejiang province, has been named among Zhejiang's first batch of pilot high-end data annotation bases.

The base will be built at the Wuzhen High-Tech Industrial Park, aiming to strengthen the region's role in the data-driven economy. Data annotation, which involves labeling large volumes of data to train AI, is seen as a key link in the AI industry chain.

As the permanent host region of the World Internet Conference, Wuzhen has already established computing infrastructure, including the Light of Wuzhen national supercomputing center, which provides strong support for data processing and AI training.

Wuzhen has attracted major digital economy companies in recent years, forming an industrial cluster covering sectors such as smart vehicles, biomedicine, and robotics. By the end of 2025, the park had gathered 369 digital economy enterprises, with output from industrial enterprises above the designated size — enterprises with annual revenue of at least 20 million yuan (about $3 million) — accounting for more than half of total output.

Under the pilot plan, Wuzhen will focus on technology innovation, industry applications, talent development, and ecosystem building. By 2027, the park is expected to become a leading data annotation base in the Yangtze River Delta region, supporting high-quality AI data supply and industrial growth.
