Indeed. I just hope that ASML would end up in the "unreliable supplier list" so a legal measure that hinders its access to China and domestic supplier get preferable position.It's an effective strategy. Within Chinese government, there are lots of westernized market-oriented liberals who favour foreign products while looking down at domestic alternatives. Many faithfully worship buying oversea is much better than building its own because it shows up on economic performance indicators much faster. Better KPI usually results in better chances of promotion.
Since Chinese DUV technology is appearing. ASML is just gaming the system, hoping those liberals would again lobby for them. This strategy really depends on how serious china is about promoting domestic chip alternatives. If the government doesn't take actions to protect fragile 100% indigenous chip manufacturing, foreign suppliers have a fair chance. I say that because so far i haven't seen any legal requirements for Chinese foundries to use at least some indigenous machines. Since people usually follow their own interest first, legal requirements are necessary.
