The 4th Global Digital Trade Expo will open from Sept 25 to 29 in Hangzhou — capital of East China's Zhejiang province — unveiling over 30 cutting-edge technologies, including humanoid robot livestreaming sessions and AI-driven cultural services.

As China's only national-level expo dedicated to digital trade, it highlights the city's role as a digital innovation hub.

Ahead of the event, local firms showcased breakthroughs currently driving the sector:

Manufacturer Udeer's sweeping robots, powered by a Master 2000 embodied intelligence chip, are already in demand across Europe with orders worth 600 million yuan ($84.33 million).

Cloud-based electronic signature solutions supplier eSign processes 30 million digital signatures daily and has developed a contract AI model. It automates drafting, reviews and management, aiming to give small and medium-sized enterprises equal legal footing with large companies.

Picocom, a baseband semiconductors and software specialist, has developed the PC802 baseband chip. It's China's only mass-produced chip enabling satellite-ground communications, supporting both satellite networks and terrestrial systems.

With digital trade volume reaching 160 billion yuan in the first half of 2025, up 16 percent year-on-year, Hangzhou is consolidating its place as a key node in the global digital economy.
