Which is not something your government can forbid or even verify, they have no way of enforcing anything under other jurisdictions. Whatever company says it did or didn't do there - the government has no choice but to believe them.

Look, I'm a Libertarian as I stated before, I do not even want a government to exist as they are oppressive by nature but I recognise that there's brutal geopolitical competition among world powers.

I can't say with the little information I've got if it is necessary or not but I understand the rationale whereby someone might implement this because they are not willing to bet the survival of their people or their nation on the goodwill of others.
