The story so far

The move follows years of U.S. export restrictions that have limited Chinese access to machines from Dutch supplier ASML. Industry analysts say the breakthrough could tighten competition for global chipmakers and pressure big‑tech firms that depend on advanced semiconductors.

Bloomberg notes the technology narrows the gap with leading manufacturers, while Fortune warns that Chinese chipmakers may trigger a sell‑off in global tech equities. Reuters reports the development puts ASML in the crosshairs of the ongoing U.S.–China squeeze.

Observers expect the next step to be scaling the tools for high‑volume fabs and monitoring any policy response from Washington.
