July 1 is almost here, and it helps to be clear about what the date is and isn’t. Under Article 34.7 of the United States–Mexico–Canada Agreement (USMCA) (T-MEC), it marks the agreement’s sixth anniversary and the formal start of the first Joint Review—not a deadline to finish it. Both U.S. Trade Representative Jamieson Greer and Secretary of Economy Marcelo Ebrard have said as much, signaling that talks will run for months. For Mexico, that long horizon is the whole point. Played defensively, the revision threatens the stability that has made Mexico a magnet for investment. Played well, it does the opposite: it turns the very rules being rewritten into a reason for even more investment to land on Mexican soil.
The groundwork has already been laid down. The first round ran May 27–29 in Mexico City, the second June 15–17 in Washington, capped by a June 18 meeting between Greer and Ebrard. The topics so far have been rules of origin for industrial goods—steel, aluminum and autos chief among them—and economic security, with agriculture, labor and the environment opened at a conceptual level. The second round even delivered the review’s first tangible result: a committee to review how the USMCA’s sectoral annexes are implemented and to improve regulatory compatibility. A third round will take place the week of July 20 in Mexico City.
Mexico’s formal position is built around certainty. In his June 1 letter to Ambassador Greer, Ebrard asked to extend the treaty for another 16 years, eliminate the Section 232 tariffs on steel and aluminum and deepen supply-chain resilience while reducing the region’s dependence on Asia. The ask is not improvised—it rests on months of consultations across 30 sectoral and 32 state forums, where the business community broadly backed both the agreement and its renewal. Stability, in this telling, is what keeps investors betting on Mexican production.
Washington, predictably, is playing a different game, framing the talks around its trade deficit and treating tariffs as a tool to keep rather than a problem to remove. That friction is real, and it touches several of Mexico’s sensitivities at once—from genetically modified corn, where the United States already won a USMCA panel, to autos, where the United States wants vehicles to carry 50% American content and regional content lifted from 75% to 82%. Corn is the most visible example; the real story is how broadly the rewrite could reach.
And here is where the Mexican perspective shifts from defense to offense. Tougher rules of origin are usually read as a burden, but for Mexico they can cut the other way. If a vehicle must contain far more North American content to qualify for preferential access, the global manufacturers that need it gain a powerful reason to build where it is most competitive—increasingly Mexico. And every push to cut reliance on China is, in effect, an invitation to bring production closer to home.
One catch may be in the wording. A higher regional threshold steers investment across North America, Mexico included; a U.S.-only carve-out would do the opposite. Either way, higher thresholds and timelines need to be calibrated carefully because supply chains cannot be reconfigured overnight. Further, some Chinese investments have benefited workers and communities in Mexico. Shaping the rules of origin is where Mexico’s negotiators can win the most.
None of this works in isolation, which is why the empty chair matters. Canada has not been in the room for either round; Washington is running the review as a bilateral track, leaving Ottawa to make its case from the sidelines, which it did on June 1 by recommending the same 16-year renewal Mexico wants. A united Mexican-Canadian front would strengthen the case for stability, but being picked off one neighbor at a time is precisely how the trilateral logic of the agreement gets hollowed out. Keeping Canada aligned, without antagonizing a Washington that prefers to negotiate separately, is a balance Mexico cannot ignore.
It also means accepting that certainty won’t likely arrive on a single piece of paper this summer. Experts argued that no document is magic enough to guarantee predictability now, and that annual review cycles might be the “least-bad” route to real alignment. That may be the terrain Mexico has to work with—so the smarter play to keep reframing the conversation around the one place all three capitals agree: North America cannot compete with China while pulling in three directions. Economic security and nearshoring are not just U.S. talking points; they are squarely in Mexico’s interest.
The next stop is Mexico City in late , where July 1 will quietly turn the review from preparation into process. It will begin to reveal whether this hardens into a stop-and-go fight over tariffs and content rules, or whether the parties agree swiftly agree on a way forward.. Either way, Mexico’s bet is not only on certainty but on opportunity—on its ability to turn a contested revision into the next wave of investment. The job now is to hold that position long enough for the rest of the region to come around to it.
