In this episode, Mariana speaks with Ken Smith, the former head negotiator from the Mexico side of the USMCA agreement and with Scott Miller co-host of The Trade Guys, a CSIS podcast specializing in trade policies.  They talk about the good, the bad and the ugly of USMCA as it approaches its third year anniversary, and how it differs from the former NAFTA. They also discuss the importance of USMCA’s dispute settlement mechanism and why the U.S.government hasn’t called Mexico to a panel regarding bio corn and the country’s nationalistic energy policies. They also speak about the potential damage caused by the U.S. for not abiding by the rulings of the panel over its interpretation of the rules of origin in the auto sector, and about what needs to be done to strengthen the rules that underpin trade and investment in North America.
