The North American Free Trade Agreement (NAFTA)
called for phasing out impediments to trade between
Canada, Mexico, and the United States over a 15-year
period beginning in 1994.
For Mexico, the ratio of export to GDP has increased
dramatically from 2.2% in 1973 to 31.7% in 2011.
The increased trade has resulted in increased numbers
of jobs and a higher standard of living for all member
nations.
