China’s EAST Tokamak Marks 20 Years, Over 160,000 Plasma Runs

EAST's two-decade run matters less as a fusion milestone than as evidence of compounding institutional capability: a self-designed, fully superconducting non-circular tokamak sustained across 160,000 plasma shots is a data-generation engine, not a one-off result. That distinction is what separates fusion programmes with a credible iteration loop from those relying on imported designs. The open question is whether this operational depth translates into physics regimes relevant to a power plant, and how much of it feeds China's broader fusion supply chain.
