Sheinbaum walks into the USMCA review having already tariffed China to please Washington
Mexico dodged Trump's reciprocal tariffs; now the July 1 joint review turns on whether it can keep China out of North America's supply chain
Summary
Claudia Sheinbaum enters the mandatory USMCA joint review — statutorily triggered 1 July 2026 — having pre-positioned Mexico toward Washington. Mexico was largely spared Trump's reciprocal-tariff wave (a White House action wound down certain IEEPA duties while keeping the USMCA exemption and a 25% rate on non-qualifying goods), and from 1 January imposed tariffs up to 50% on ~1,400 products from countries without an FTA, hitting China's cars, auto parts and steel and lifting low-value parcel taxes on Shein and Temu. Washington has reframed the review as a China test: can Mexico stay North America's factory floor without being a "side door" for Chinese content? Sheinbaum, polling 63–85% at home, calls it a "review, not termination" and refuses to rush past the July 1 deadline.
The split
Mexico's mañanera line (carried by [[Reforma]] and others) sells a relationship "based on collaboration but with respect" and a deal that "protects the USMCA." The Diplomat and CSIS, from Washington, read Mexico's anti-China tariffs as pre-emptive alignment and warn energy (CFE priority dispatch, the 54% state stake) and Chinese content are the real fault lines. Foreign Policy stresses cartel designations bleeding into trade. Beijing protested and urged Mexico to reverse the hikes — the omitted third party whose interests Mexico just traded away.
By the numbers
- July 1, 2026 — statutory USMCA joint-review trigger.
- 16 years — extension on offer if the review succeeds; else a slide to annual reviews.
- Up to 50% — Mexican tariffs on ~1,400 products from non-FTA countries, effective 1 Jan 2026.
- ~8.6% — share of Mexican imports touched by the tariff package.
- 33.5% — raised tax on low-value parcels (Shein/Temu).
- 63–85% — Sheinbaum's domestic approval range.
Why it matters
The review decides whether North American Trade Rules lock in for 16 years or fray into annual uncertainty — shaping nearshoring, auto supply chains and Mexico's room to trade with China. Sheinbaum is wagering that visibly tariffing Beijing buys her leverage on energy and content rules without forfeiting a major export market.
What to watch
- Whether the review concludes by July 1 or slides into rolling annual reviews.
- US demands on CFE priority dispatch and the 54% state-generation stake.
- New rules-of-origin / Chinese-content thresholds for autos.
- China's retaliation or investment response to Mexico's tariffs.
