The comment you’re replying to doesn’t mention EU, so this nitpick doesn’t make much sense.

Norway integrated GDPR into its own legal system: https://lovdata.no/dokument/NL/lov/2018-06-15-38

Didn't mention EU, but to be specific: members of the EU or the EEA.

GDPR was implemented in the EU and in the EEA, of which Norway is a member of.
