The Dutch government just explicitly denied any foreign involvement, while at the same time acknowledging that a few years ago the export restrictions for ASML were implemented because of US involvement.
Tbh, I don't know what the truth is. I'm a Dutch citizen and what is happening now is unheard of. I don't know what the motivation is and it seems to have happened out of the blue. Maybe the motivation literally is protecting the European semiconductor industry.
I seriously doubt it is aimed against China. Europe is not looking for a trade war, especially now that the US is an unpredictable ally (if they still are) and basically the whole geopolitical situation is shifting. China is also not a topic for Dutch politicians, so it's not winning anyone votes.
