Thank you for the question.
I will respond, but I will also invite my colleague Mr. Marsland to comment, since the Department of Finance negotiates these treaties. Our role is to administer them. We each play a role in this area.
Our interaction with foreign authorities is governed by over 100 international agreements. With respect to your interpretation, I'm not in a position to say whether or not the United States would accept our delegation. That is a question we would have to ask them. Customs and traditions dictate that it usually remains at the national level. So these are national agreements, not subnational agreements.
If Mr. Marsland wishes to add something, I will give him the floor.
