I'm not sure what type of airtight assurances you could get, beyond two governments standing up and signing an agreement. All of these agreements have a dispute-settlement mechanism. So I would suggest that if an agreement comes to this committee for review, you look carefully at the dispute settlement mechanism.
But I don't think there is a next better thing that you would get. We negotiate inside the agreement. We try to get as many most favoured nation clauses as possible. This way, if the U.S. or Europe or other large markets are able to get more, we're able to piggyback.
