I wrote an article shortly after the Trump administration took office discussing their official withdrawal from the Trans-Pacific Partnership (TPP). This answered my own rhetorical question of whether the U.S. withdrawal effectively killed all new multilateral agreements with the response, “it depends on who you ask.” Since then, many (including my colleagues) have written how the “America First” protectionism approach stifles global trade. Late last month, as President Trump agreed to renegotiate the North American Free Trade Agreement (NAFTA) rather than end it, in contrast to his statements even before taking office, my follow-up article will not dwell upon protectionism and trade. Rather, this article will evaluate how the “everything is negotiable approach” adopted by the Trump administration may affect the success of the current U.S. trade agenda.

In a segment on Trump’s first 100 days in office, one news commentator described the current administration’s negotiation approach–(including trade matters)–as essentially a three-step process:

1. Take an extreme approach that appears unreasonable;

2. Move toward dialogue; and

3. Compromise and negotiate a reasonable outcome.

Sometimes the approach works and we obtain the outcome the president wants for U.S. trade policy, which is really all you can ask when negotiating with other nations on trade issues.

Where NAFTA is concerned, it appears the U.S., Mexico and Canada are publicly stating support to modernize the agreement since Trump announced he will renegotiate rather than terminate the pact. Mexico’s Foreign Minister Luis Videgaray stated that he “believe[s] that all the conditions to reach a good negotiation exist, that will suit Mexico… and that is also good for the region, for both Canada and the United States.” Canada is also “ready to come to the table at any time” once NAFTA negotiation begins among the three nations, reported Alex Lawrence, spokesman for Canadian Foreign Minister Chrystia Freeland.

In the renegotiation, President Trump will likely try to tighten NAFTA rules of origin to ensure that these rules promote U.S. manufacturing and jobs (a common theme coming from his administration) by tightening the rules of origin under NAFTA. He may try to limit the amount of non-regional content that is permitted in complex manufactured goods and still considered NAFTA-eligible. For example, Trump may specify that even Chinese components are allowed in complex manufactured products under the NAFTA rules without changing the country of origin from Mexican or Canadian. Trump has often focused his ire on China as a bad actor in their trade practices. He may use the China illustration under the current NAFTA rules as leverage in negotiating the new NAFTA rules with Mexico and Canada.

Trump will also will likely revisit antidumping and countervailing duty laws. Trade remedies under NAFTA are currently reviewed by a NAFTA panel, rather than the courts of each country, like antidumping or countervailing duty cases arising from products originating from other countries. The administration may insist that NAFTA trade remedies cases are reviewed judicially like all others, particularly in light of Trump’s executive order focusing on the “enhanced collection and enforcement of antidumping and countervailing duties and violations of trade and customs laws,” aimed to curtail unfair trade practices.

Mexico’s primary bargaining chip with the Trump administration is need of the U.S. to get Mexico’s help on border security and immigration. “All issues that define our bilateral relationship are on the table, including security, migration and trade,” said Mexican President Enrique Pena Nieto. Trump will need to compromise in the negotiation, but at least the parties have “moved toward dialogue” and will negotiate, rather than walk away from NAFTA.

There is risk. However, it seems that renegotiation of the trade deal is moving the administration’s trade agenda along a path far safer than walking away completely, which many considered extreme. So is everything in trade negotiable? In the case of NAFTA, I guess we will wait and see.
