Our role with the negotiators is simply to get briefings from them and then to provide input. When we do meet with other country delegations, we typically will phone our negotiators and say what is important for the other country to hear from us and what would help us to say if we talked to that country, or if we talked to any other delegation. So I would characterize it as a partnership. That doesn't mean we always get what we want, because they do have to negotiate, but I would characterize it as a strong partnership.
