Mexico's Foreign Relations Secretary, Alicia Bárcena, expressed concerns that these orange buoys could violate treaties between the two countries that govern their boundaries and water resources.
"We are sending a mission, a territorial inspection to see where the buoys are located … to carry out this topographical survey to verify that they do not cross into Mexican territory," stated Bárcena.
She also mentioned the placement of barbed wire fencing on a low-lying island in the river near Eagle Pass, Texas, as another point of contention.
The Texas Department of Public Safety defended the barriers, stating that they are positioned a foot below the water line, making it challenging for individuals to swim past them.
"The buoys go down a foot below the water line, so anyone wanting to get past them would have to swim at least that far down," said Texas Department of Public Safety Spokesman Lt. Chris Olivarez.
However, critics have expressed concerns about the increased risk of migrant drownings, while environmental groups have raised objections regarding potential impacts on the river.
