The US is skeptical that the most advanced EUV lithography machine, $ASML , might have slipped into China.

However, ASML denies it. Given the machine's massive size and its automated remote monitoring system, it's nearly impossible for clients to move or operate the equipment without ASML's tech crew on site.

If I remember correctly, the machine locks up automatically if it experiences any unusual vibrations, right?

This whole situation feels like fake news. Maybe Trump is trying to play the same old game, like he did with Intel, to get the US government a stake in ASML.
