Last week, trucks crossing the U.S.-Mexico border into Texas were met with safety inspections causing wait times as long as 24 hours and stalling about 19,000 trucks loaded with $1.9 billion worth of goods.

On Oct. 10, Mexico’s President Andrés Manuel López Obrador sent a diplomatic note in protest of Texas Gov. Greg Abbott’s inspection initiative — meant to crack down on undocumented immigrants and drugs — saying it obstructs and harms both nations’ economic and commercial activity.

“This measure has generated a crisis that has resulted in closures, detours, longer crossing times and significant reductions in the export volumes of different products from Mexico to the United States,” CANACAR, a trade association representing individual carriers within the Mexican trucking industry, said, according to a Reuters report.

On Sept. 29, the Wall Street Journal reported on the impact of the flow of trade and bottlenecks, which extend into rail.
