Answer:
Step-by-step explanation:
Normally the two main reasons for an international trade barrier to be implemented is so that a precious good/resource is maintained and protected within the borders or in order to retaliate against a trade partner for something. Therefore Mexico most likely would implement a trade barrier for one of these two reasons. Most likely another trade partner has increased the Mexican import fees for one of their products, and as retaliation, Mexico would place a trade barrier on one of the goods that "that" specific country requires.
