Twenty years after its formation, the North American Free Trade Agreement (NAFTA) remains a useful, if incomplete, expression of the economic ties between Mexico, Canada, and the United States. It has also proven itself to be of great importance in partially achieving the full economic potential of the North American region. Now, we must deepen North American economic integration in order to compete more effectively globally. That means common regulations and standards on products manufactured in North America, negotiating as a bloc with Asian and Europe, making both borders function more efficiently, investing in physical infrastructure, supporting innovation and education, facilitating labor mobility, and aligning our energy policies.
