Evidence of the development of regional supply chains and of the close-knit economic relationships that have been formed within the North American region can be seen in the considerable growth of Mexican non-oil exports to the US and of México’s imports of intermediate goods from the US since NAFTA went into effect.
México is currently the second most important source for US imports and the second most important destination for US exports.1 Furthermore, México is among the top two export destinations for at least thirty US states, including Texas.2 In some cases, México buys over ninety percent of some states’ overall export sales of particular goods.3 The integration brought about by NAFTA through the deepening of commercial and production ties has benefited all its members.
