> As far as taxation and shipping go, not really. The Law of the Sea grants the right of innocent passage to all ships, so a country can't tax or harass ships merely passing through its waters. This holds for territorial waters as well as the Exclusive Economic Zone.

I was unclear on the tax point, sorry; the extending of the baseline may determine the entitlement to tax resource use and extraction. You are correct in that UNCLOS prohibits tax of innocent passage.

On shipping it is also my understanding that UNCLOS grants broad rights to passage, though these are subject to those exceptions you mentioned, as well as an exception for "internal waters". I believe a couple cases turned on islands (which I am sure you also know about better than I do– my background is academic and dated!).

As an interesting aside, the word tariff comes from Tarifa, Spain, which would tax ships passing through the Strait of Gibraltar.

Just for ease of any future readers, the actual convention is not horribly complex, and is at: http://www.un.org/depts/los/convention_agreements/texts/uncl...
