Answer:
According to the chart, we can see that a change in international trade policy has increased trade between the USA and Mexico.
Step-by-step explanation:
The proximity between the USA and Mexico was a positive point for establishing an efficient commercial relationship between the two countries. However, this trade was weakly and deficiently established, due to an international trade policy of little benefit to both countries. However, a change in this policy, transformed the commercial relationship between the two countries and something very relevant, which narrowed the international trade and promoted benefits for both countries.
