That is what I’m saying: it is exactly analogous to the government of Sarawak declaring that only what is made within its borders can be called something... if it is made outside its borders, it is only within its borders that that thing can be rejected as being not worthy of the name. It’s the accords and the relationship between entities of various kinds (some of them sovereign, some of them not) which gives or denies this stipulation any power whatsoever. To wit: the Sarawak government is entirely free to impound cake blessed with the hallowed name if it is made in the state of Selangor and shipped to within Sarawak, but decrying Selangor-produced cake sold in Kelantan is entirely outside the scope of its power because all of that occurs beyond its borders, and is therefore ineffective unless there is a national government and/or trade agreements that overarch all the territories. It’s exactly the same for national, EU, and international trade agreements.
