(AI-generated image)* Mexico's Secretariat of Economy confirmed Nov. 14, 2026, that the government will not negotiate a free trade deal with China, aligning industrial policy with North American trade rules. The stance shields cross-border supply chains governed by the United States-Mexico-Canada Agreement (USMCA). United States President Donald Trump threatened earlier in the week to double tariffs on Mexican imports. Mexico already levies import tariffs between 5% and 50% on 1,463 industrial lines from non-FTA countries under a decree enacted Jan. 1, 2026. The tariff schedule directly targets automotive components, steel, plastics and electrical subassemblies. The presidential tariff decree amends the General Import and Export Tax Law (LIGIE). Mexican customs data showed imports across those 1,463 tariff lines fell 21.7% in the first half of 2026, while shipments from China dropped 26.3%. President Claudia Sheinbaum told a morning press briefing on Nov. 12, 2026, that Mexico remains committed to North American manufacturing integration. The federal industrial strategy, Plan México, mandates a 15% increase in domestic value content in automotive and semiconductor value chains. Plan México targets 50% domestic procurement across strategic sectors. The Mexican Automotive Industry Association reported that national auto parts production reached $11.118 billion in August 2026. Washington has demanded stricter regional value content thresholds ahead of the scheduled USMCA joint review. Under existing rules, passenger cars must meet a 75% North American regional value threshold to enter the United States duty-free. United States negotiators have pressed to lift that regional content requirement to 80%. United States trade officials have also proposed establishing a minimum 50% United States domestic content requirement for finished motor vehicles. Those rules directly curb Chinese component manufacturers that established Mexican operations to serve the United States. Chinese foreign direct investment in Mexican industrial property expanded to cover more than 1.8 million square meters. Ningbo Tuopu Group, a chassis and interior supplier based in Ningbo, China, operates a component plant in Mexico with an annual capacity target of 300,000 units. Tesla accounts for 35% to 40% of Tuopu's total revenue. Tuopu achieved 62% local procurement at its Mexican facility to satisfy rules of origin. The supplier faces higher production costs if Washington lifts regional thresholds beyond 75% or Mexico excludes Chinese subcomponents. Contemporary Amperex Technology Co., Limited (CATL), the world's largest electric vehicle battery manufacturer, booked 253 billion yuan ($36.4 billion) in revenue during 2025. CATL has delayed direct cell manufacturing investments in Mexico due to regulatory uncertainty. Chinese automaker BYD Company, which reported 804 billion yuan ($116 billion) in 2025 revenue, suspended plans to build a 150,000-unit assembly factory in Mexico. BYD executives had explored buying an existing 230,000-unit joint venture plant in Aguascalientes to bypass approvals. The Mexican Customs Law reform enacted Jan. 1, 2026, established joint liability for Mexican customs brokers. Brokers must verify component origins, preventing Chinese firms from rerouting unprocessed parts under preferential temporary import programs. Mexico's trade deficit with China reached roughly $14 of imports for every dollar of exports. Sheinbaum plans to address supply chain localization at the Asia-Pacific Economic Cooperation (APEC) summit in Shenzhen, China, on Nov. 17-19, 2026. Economy Secretary Marcelo Ebrard will accompany the Mexican delegation to Shenzhen for bilateral discussions with Chinese commerce officials. Ebrard confirmed the meetings will focus on commercial rules without compromising Mexico's commitments to Canada and the United States. Mexican officials will review existing tariff exemptions under the non-FTA decree before the current tariff schedule expires on Dec. 31, 2026. Formal trilateral consultations on USMCA rules of origin open in Washington ahead of the agreement's mandatory review. The Secretariat of Economy has not published an official decree initiating an additional administrative investigation into Chinese components on Nov. 14, 2026. Mexican authorities have not released draft tariff modifications beyond the existing 1,463-item schedule. Mexican vehicle shipments to the United States contain an average of 40% United States-made parts, according to the Center for Strategic and International Studies. Mexican passenger car shipments to the United States fell 20% in value between January and July 2026. The Mexican federal government maintains that trade compliance with Washington takes precedence over bilateral agreements with Asian trading partners. Sheinbaum reiterated that domestic procurement targets under Plan México remain the central tool to manage external trade friction. ## Impact map | Event | Korea | China | Japan | Global impact | | --- | --- | --- | --- | --- | | Mexico non-FTA tariffs and USMCA auto rules | Hyundai Mobis and Korean part makers face 10-50% duties on non-originating inputs | Tuopu and BYD face capped Mexican nearshoring as USMCA rules target Chinese content | Nissan and Denso adjust North American parts purchasing to meet 75% local threshold | North American automotive BOM climbs as suppliers substitute Chinese components | ## In this story - **Companies:** BYD Company, Contemporary Amperex Technology, Ningbo Tuopu Group, Tesla - **Tickers:** 002594.SZ, 300750.SZ, 601689.SS, TSLA - **Policy:** Tariffs, Local Content Rules - **Impact:** Supply Chain, Compliance, Cost Structure ## Primary sources 1. www.gob.mx 2. mexiconewsdaily.com 3. ytn.co.kr 4. kita.net 5. ibtimes.com --- Cite as: East Asia Brief, "Mexico rejects China trade pact under Trump tariff threat," November 15, 2026. https://eastasiabrief.com/trade-policy/mexico-rejects-china-trade-pact-under-trump-tariff-threat-1446
