Forcedshoring's Next Test: China in the US-Mexico Equation

For three consecutive years, Mexico has been the United States' largest trading partner, and 2025 confirmed just how central that relationship has become. Two-way commerce between the two countries reached a record US$872.83 billion, a 3.9% increase over 2024, comfortably ahead of Canada (US$712.76 billion) and China (US$414.69 billion), according to U.S. Census Bureau data reported by FreightWaves. Mexico's own trade figures tell a complementary story: the country closed 2025 with record exports of US$664.84 billion, up 7.6% year-over-year, more than 80% of it bound for the United States, and posted its first trade surplus in four years.

Yet, none of these figures can be read purely bilaterally anymore. Every negotiating round of the 2026 USMCA joint review, every tariff schedule Mexico publishes, and every foreign direct investment announcement is now shaped as much by Washington's anxiety about China as by the substance of the US-Mexico relationship itself. China has become the silent third party at every table where Mexico and the United States sit down to talk trade.

The clearest evidence came on July 1, 2026, the date the USMCA's mandatory six-year review commenced. The Office of the US Trade Representative stated plainly that “the United States did not agree to renew the USMCA in its current form,” even as Mexico and Canada both confirmed their support for extending the agreement another 16 years under the treaty's built-in mechanism. The USMCA remains legally in force — its preferential tariffs, dispute-resolution provisions and rules of origin are all still operative — but the joint review has given way to a slower, more adversarial bilateral track. The United States and Mexico held a third round of negotiations in late July and have scheduled a fourth for September, centered on automobiles, steel, aluminum and agriculture. Annual reviews will now recur through 2036, keeping the relationship permanently under negotiation.

China sits at the center of what Washington actually wants from those talks. Research from Rice University's Baker Institute identifies the core US proposals for the review: tighter rules of origin for industrial goods, designed specifically to prevent Chinese components from entering North America through Mexican assembly; a possible investment-screening mechanism to restrict Chinese capital in strategic sectors; and bans on Chinese-connected vehicle software mirroring existing US restrictions. Canada, for its part, aligned early, imposing 100% tariffs on Chinese electric vehicles and 25% on Chinese steel and aluminum back in August 2024. The message to Mexico is unambiguous: continued preferential access to the U.S. market depends on demonstrable distance from Chinese supply chains, not favorable tariff math alone.

Mexico has moved to close that gap, and the numbers show both the urgency and the awkwardness of the position. Tariffs of 5% to 50% on more than 1,400 product lines from countries without a free trade agreement — chiefly China, but also India, South Korea, Thailand, Indonesia, Brazil, South Africa and the UAE — took effect Jan. 1, 2025, covering vehicles, steel, textiles, footwear, furniture, toys, aluminum and glass. In December 2025, the Mexican Congress authorized a further escalation, again reaching 50% on additional Chinese categories. US Treasury Secretary Scott Bessent publicly welcomed the move and urged Canada to adopt similar measures to “fortress North America” against Chinese imports — an endorsement that also reads, as several analysts have noted, as evidence that Mexico's tariff policy is being calibrated as much for Washington's benefit as its own.

The underlying trade relationship with China explains the pressure. During 2025 alone, Mexico imported roughly US$133 billion in Chinese goods while exporting just US$10 billion back — an imbalance dominated on the export side by copper (40.5% of shipments) and on the import side by telephones, machine parts and motor vehicles. Mexican authorities have simultaneously stepped up enforcement, opening 11 anti-dumping investigations against Chinese products in 2025, roughly double the prior year, and tightening oversight of the IMMEX maquiladora program amid US concern that Mexico has become a transshipment point for goods seeking to dodge American tariffs. The chill has already claimed a marquee project: Chinese automaker BYD paused or canceled its planned Mexican factory in 2025 as the geopolitical temperature rose.

Autos are where this pressure is most concentrated, because they are also where Mexico has the most to lose and the most to prove. Mexico held a record 46.2% share of US auto parts imports in 2025, the highest ever recorded, built on competitive labor costs, logistics efficiency and the regulatory certainty of USMCA rules of origin. That dominance is precisely why the sector has become the review's most contentious front: US officials have publicly accused Mexican suppliers of “masking” Chinese-origin components to qualify for USMCA preferences, and the automotive chapter is expected to anchor whatever rules-of-origin tightening emerges from the September round of talks. A record market share, in this context, is also a record-sized target.

This is the environment in which Mexico's investment and growth numbers need to be read. Foreign direct investment reached US$40.9 billion in 2025, a 14.5% increase over the same period in 2024 and already ahead of that full year's total of roughly US$37 billion, according to figures presented by Economy Minister Marcelo Ebrard. New investment, as opposed to reinvested earnings, more than tripled to US$6.5 billion. That capital is arriving even as Mexico's economy grew only 0.8% in 2025, with the Bank of Mexico and the OECD projecting a modest recovery to between 1.4% and 1.6% in 2026. Investors, in other words, are betting on Mexico's structural position in a reorganized North American supply chain, not on near-term domestic demand.

That structural position is precisely what this publication's readers have seen described as “Forcedshoring:” the systematic, geopolitically driven relocation of supply chains toward jurisdictions of legal and political certainty, distinct from the voluntary, cost-driven logic of nearshoring's first wave. The China variable is what makes Forcedshoring binding rather than optional. Mexico cannot simply present low tariffs and USMCA membership as sufficient; it must actively prove, line by line and shipment by shipment, that what crosses the border northward is genuinely North American in origin. The rules-of-origin fights, the anti-dumping filings and the IMMEX audits are not bureaucratic noise. They are the price of admission the United States is now charging for continued preferential treatment.

For Mexican business leaders and policymakers, the strategic response is not to choose between China and the United States in the abstract, but to make Mexico's compliance infrastructure — customs verification, supply-chain traceability, rules-of-origin documentation — a competitive asset rather than a liability. The country that can prove its manufacturing content fastest and most transparently will be the one still standing preferentially inside the USMCA framework when the next annual review comes around.

Diversification remains the other half of the equation, and here Mexico has finally begun to act rather than merely discuss. On July 14, 2026, the Council of the European Union gave its final approval to the modernized EU-Mexico Global Agreement, clearing the way for entry into force after years of delay. It will not, and never will, replace the US market — Europe still buys a fraction of what the United States does — but it gives Mexico a second serious anchor at precisely the moment its primary trading relationship has become conditional on how convincingly it can distance itself from China. Mexico's numbers, for now, remain extraordinary: record trade, record exports, record investment. Whether they stay that way depends less on Washington or Beijing than on Mexico's own capacity to manage the triangle it now occupies.
