The Line Sheinbaum Drew on Sovereignty
Ahead of the USMCA Review

← Back to Latin America News

Whenever U.S. Ambassador to Mexico Ronald Johnson weighs in on cartel policy inside Mexico, President Claudia Sheinbaum has been quick to push back. Her words — stay out of our internal affairs — are delivered in a sharp tone stripped of diplomatic cushioning. With the formal USMCA review set for July, Sheinbaum's stance carries a political meaning that goes beyond ordinary diplomatic friction.

What Happened

According to reports, Sheinbaum named the American 'far right' and held it responsible for the worsening of U.S.-Mexico relations. This is both an external critique and a message aimed at home, because a tough line toward the United States works as a way to sustain approval ratings and appeals to national pride.

Ambassador Johnson's remarks are said to have been genuinely intrusive. The framing that cartel policy is 'not political' carried an implication of routing around the Mexican government's own judgment. Sheinbaum's rebuttal was less a ceremonial gesture than an attempt to set the terms of the negotiation herself.

Background

At nearly the same time she criticized the ambassador, Sheinbaum reportedly met JPMorgan CEO Jamie Dimon to discuss investment and economic opportunity in Mexico. Tough talk and the courting of capital running side by side may look contradictory, but it is best understood as a deliberate division of channels. To the U.S. government she presses the principle of sovereignty; to private capital she opens the door as a strategic partner. The message that the decision rests with Mexico is conveyed through several channels at once.

Beyond this political context lies the first joint USMCA review, beginning in July 2026. Bilaterally, the United States and Mexico have reportedly already opened negotiating rounds — on economic security and rules of origin in May, on agriculture and a 'level playing field' in June. The U.S. Trade Representative's June 2 proposal for additional tariffs tied to forced labor, which would cover Mexico on some goods, is one such instrument of pressure.

The Stakes / The Contrast

Sheinbaum's discourse of sovereignty serves to mark, at home and abroad, the line beyond which she will not retreat in this negotiation. Yet she is not all toughness. More than 70 percent of Mexico's exports go to the United States, and walking away from USMCA would be costly for both sides. She performs the posture of 'we will take our seat, but we set the terms,' while in fact maneuvering within a narrow margin.

For Sheinbaum, who must carry on the line of her predecessor López Obrador (AMLO) while signaling that she is 'not the same,' putting sovereignty front and center is also a way of giving her government its own character. A display of strength abroad, and concrete economic interest at home — how she balances the two will be tested through the summer review.

The Author's View

In Latin America I have felt, again and again, the weight a country places on the word 'sovereignty.' For these nations sovereignty is not an abstract ideal but something close to a lived conviction: the refusal to let outsiders decide the shape of their own society. Who gets to decide social policy and the form of public institutions — that question runs quietly beneath every trade negotiation.

That is why I would rather not dismiss Sheinbaum's split between 'hard words' and 'an open door' as mere double-talk. Drawing a line against outside pressure while still inviting investment for the sake of her own economy and her people's lives — a leader entrusted with governing the region is trying, within a narrow margin, to reconcile sovereignty with reality. It is that difficulty I want to keep my eyes on.

Glossary

The USMCA (United States–Mexico–Canada Agreement) is the free-trade agreement among the three North American countries that replaced NAFTA in 2020. It includes a mechanism of periodic 'joint review,' the first of which begins in July 2026. Rules of origin are the criteria that determine where and to what degree a product must be made in order to qualify for the agreement's tariff preferences.

Speaking of sovereignty while opening the door to investment — what Sheinbaum draws is not a rupture but a renegotiation of stance.
