Selling euv to China will let them reverse engineer it and put a state sponsored competitor on the market within 5 years.
Frankly if Europe really meant business they’d put a heavy export tariff on it, so the chip companies have to produce in Europe.
Nope, asml machines are of such complexity that no sane country/company would try to reverse engineer it.
But China isn’t driven by conventional economics nor honest trade. They want everyone else to become dependent on them as a way to get power and soft colonise others.
