Turning this around...

...could probably very easily be done:

...officials now say that members of the border Chambers of Commerce from Mexicali in Baja California to Matamoros across from Brownsville are asking that all Mexican citizens stay away from the United States on Monday.
They are asking that no Mexican national cross to shop, work or even play tourist that day.

Would that some enterprising groups along the border would organize some sort of counter-boycott, in which citizens who don't normally shop in the border towns could go shopping there for the day -- boycott the boycott, for lack of a better term. I'd bet the effect of said boycott, if there was any, could be completely neutralized.

Of course, I wouldn't be surprised if such a thing was being planned but just was not getting any media coverage...
