The remedy is always in the hands of the country of import. In this case, the first phase is in the hands of Mexico when the Chinese stuff knocks on the door, and the second phase is in the hands of the U.S., when the wheels come into the U.S. They have to be able to control with tariff codes. They have to see the stuff coming in. If they see the stuff coming into Mexico before it shows up or its equivalent shows up on their side of the border, they can pre-empt it. The pre-empting could be done through the joint monitoring approach by the three countries.
