I am writing in regard to Diana Washington's article, "Mexico data overstate weapons traced to U.S.," published by your daily on May 14.

The government of Mexico remains concerned over the flow of small arms that prolongs the drug-related violence that has plagued Ciudad Juárez and other localities for over a year. Being neighbors has presented unparalleled opportunities for both our countries for many years.

The issue of arms trafficking has always been on the bilateral agenda, as would be expected by any country geographically linked to the largest arms producer in the world.

The transnational nature of drug-trafficking makes it difficult for Mexico to successfully confront this threat on its own, especially as criminal organizations operating on both sides of the border are financed with bulk cash and armed with weapons trafficked from the U.S. into Mexico. The routes, means of transportation and concealment methods used to smuggle arms into Mexico are similar to those observed in drug-trafficking.

Your reporter's allegation that the Mexican government "handpicked" wea pons for tracing by U.S. authorities, and that the statement that 90 percent of weapons are traced back to the United States is "overblown" is a denial of reality, not to mention retrograde of an era that has long passed.

I am referring to the time when our countries would point fingers at each other and blame one another for what were really common challenges that required joint responses.

Indeed,

90 percent of all weapons seized in Mexico and successfully traced by ATF originated in the U.S. While not all serial numbers could be provided for a variety of reasons, it is only logical that Mexico, a country with an insignificant arms industry of its own, has weapons coming in from a country with the logistical ease to bring the guns in.

On the matter of arms trafficking, both countries have now recognized the negative effects that the phenomenon has on public safety on both sides of the border.

Consequently, we have unprecedented cooperation on this issue.

We welcome the reinforcement of key agencies, such as ATF, along the border. While much work remains to be done, it is sad to see counterproductive allegations that do nothing but strengthen the drug cartels that have wreaked havoc on our law enforcement, military and society.

It is important to underscore that at no moment whatsoever has the Mexican government argued that the Second Amendment to the U.S. Constitution needs to be in any way revised to address the illicit trafficking of weapons into Mexico.

In fact, the Mexican government has publicly and repeatedly emphasized that any change to the Second Amendment is a sovereign decision of the U.S. administration, Congress and the American people.

This is not a game of numbers, as any curtailment of arms flow will have a direct impact on the cartels.

In sum, the Mexican government needs the support of the U.S. to stop the illegal flow of weapons into Mexico as this would have a significant impact on and help disrupt the modus operandi of drug-trafficking organizations operating on both sides of the border, defanging them of their firepower and further fragmenting the drug syndicates.
