The Dutch company ASML is the only company to make the world's most advanced chipmaking machines. Those machines have only ever gone to US or US-friendly companies such as TSMC, Intel, Samsung, and so on. The Chinese chipmaking market hasn't had access to them—perhaps until now, that is.
According to the US Commerce Secretary Howard Lutnick, there are concerns that one of ASML's best machines might have made its way into China (via Bloomberg). Those are, reportedly, concerns that Lutnick has raised to the company's senior leaders in private meetings.
