The economy of the city is significantly based on its international trade with the United States through the USMCA agreement, and it is home to one of the most promising industrial sectors in Mexico, mainly due to the presence of maquiladoras. In Matamoros, the automotive industry hosts the assembly and accessories plants for brands such as General Motors, Ford, Chrysler, BMW, and Mercedes-Benz.

Why this record matters
The subject matters to the general reference register because the source frames it as municipal seat of Matamoros, State of Tamaulipas, Mexico. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 30, 2026. The linked authority identifier is Q738353. VIAF identifies the subject as 145144648537774718529. Authority coordinates are 25.850, -97.504. 2 of 4 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2016.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
