I’m almost certain that import and export has specific laws written for that case, considering how crucial it is to the country. GDPR is a specific new thing less than 10 years old and has no equivalent in US law.
Sorry, I may have given the impression that I mean I was questioning if there are any laws that control how interactions with other countries work. In fact my question was if there are generic laws that say “when Europe introduces some new law, the US has to follow it”.
