That's a very general question, and it's difficult to answer it in a general way.
Most of our agreements have specific and sufficient rules to protect the majority of our interests. From time to time, it is not possible to find a solution during negotiations. Barriers can arise once negotiations are completed, and they are not necessarily related to obligations set out in the agreement.
So it's not necessarily a lack of rules or the fact that the objectives or interests of our industries are not understood; it's simply that the rules in place did not contemplate the situation that arose after the agreement was negotiated.
