China has launched what it calls the world’s largest distributed AI computing network, linking data centers across a 2,000-kilometer span with near-perfect efficiency, according to Science and Technology Daily.
The Future Network Test Facility (FNTF) took more than a decade to build and is now fully operational. Beijing says the system allows distant supercomputing hubs to operate almost like a single machine, enabling faster training of large AI models, telemedicine and industrial applications.

Project director Liu Yunjie said the network’s “deterministic” architecture cuts training times by months and directly supports China’s “East Data, West Computing” strategy.
The platform spans 40 cities and can handle thousands of simultaneous experiments with ultra-low latency.
At its launch, China demonstrated a 72-terabyte scientific data transfer that finished in under two hours — a task that would take nearly two years on the regular internet.
Officials say the system will aid sectors from manufacturing to future 6G research.
