They also called on the Trump administration to continue to support NAFTA until the new trade agreement is ratified.  On March 4, House Ways and Means President Richard Neal predicted a “very hard” path through Congress for the agreement.

For the first time, the new agreement also stipulates that 40-45% of parts of a non-tariff vehicle must come from a so-called high-wage plant. These plants must pay at least $16 per hour in average wages for production workers. That`s about three times the average wage at a Mexican plant right now, and government officials hope that this provision will force automakers to buy more supplies from Canada or the United States, or raise wages in Mexico.

The threats of tariffs avoided when the China trade agreement was concluded would have doubled the blow on GDP. On December 12, 2019, the Mexican Senate adopted the revised treaty by 107 votes to 1.
