Thanks, France and Wendy.

Sounds good to me, Wendy!

Hello you two! I have just done a little research, and I believe the term you are after is 'territorial principle' as France suggested.
'The territorial principle is a foundational doctrine in public international law that grants a sovereign state exclusive authority to enact, adjudicate, and enforce laws over all persons, property, acts, and events occurring within its physical boundaries.'

I translated your two suggestions and I'm not sure.
Here she said that to have the label "French production" the most important is that the building is located in France even if the workers and the products (wool) are from abroad.

Thanks, France. Suggestions from AI:
Woman: As for industry, we believe in the right to stay on home soil.
or Woman: When it comes to industry, we're all for keeping it on our own soil.

Mark,
Speaking about industry and sheep,I've a doubt with citizenship. How about something like territorial principal?
