Yep. I'm a dual American-Dutch citizen and I've noticed that as well. You can find "American party cups" in practically every store that sells the plain white ones (I've only seen one store that breaks that rule.)
Funny enough, the Dutch ones are completely inferior, and way more expensive. They crush easily, don't separate well, and are weirdly small, not to mention several euros for a tiny package. This has annoyed me to the point where I now bring a little stack of Solo cups each time I fly to the Netherlands.
