With the aim of presenting a united front to prevent and fight counterfeiting crimes, on November 11, 2001, Banco de México and the Federal Attorney General´s Office decided to endorse a General Collaboration Agreement, which was signed on that date by the Governor of Banco de México and the Federal Attorney General, and in which both institutions committed themselves to:
 

Develop programs to prevent counterfeiting and the alteration of money or any other action that harms or endangers the secure circulation of money;
 

One of the first actions that arose from the signing of this agreement was the establishment of the Permanent Working Group Banxico–PGR, in charge of performing the activities of training, prevention, and strategic analysis regarding currency counterfeiting activity in México.

On the part of the Federal Attorney General´s Office, the areas involved in this group are: the Unit Specialized in the Investigation of Operations Performed with Illicit Resources and the Counterfeiting or Alteration of Currency (UEIORPIFAM), the Federal Investigation Agency (AFI) and the National Central Office INTERPOL-Mexico. On the part of Banco de México, the participating areas are: the General Directorate of Currency Issuance, the Legal Directorate, and the Security Directorate. All these areas collaborate closely in the fight against banknote counterfeiting through actions that lead to the establishment of links among detained subjects or investigated subjects and counterfeit banknotes.

Within the framework of this agreement, Banco de México constantly gives training courses on the identification of banknotes at the ICAP ( Institute of Professional Training ) of the Federal Attorney General´s Office and at the National Institute of Penal Sciences.

In addition, Banco de México and the Federal Attorney General´s Office conduct campaigns to prevent counterfeiting through the distribution of informative posters and through training courses.

The principles on which the cooperation between Banco de México and the Federal Attorney General´s Office are based are mainly: the responsibility for implementing in a timely manner adequate anti-counterfeiting measures in Mexico, and the commitment to perform work together, share knowledge and experience, in pursuit of the same objective—the fight against counterfeit money.

The work that Mexican authorities have done on counterfeiting has resulted in several achievements, such as:
 

The confiscation of fake 100-peso banknotes of good quality in 1998 in Nuevo León , Sonora and Tamaulipas, which led to the apprehension of eight individuals dedicated to the manufacture and distribution of the banknotes. The searches, the detection of the printing presses, and the apprehensions led to the halting of one of the most significant counterfeit operations of recent years.
 

The dismantling of a workshop in which counterfeit metal coins were manufactured, located in Xalostoc, in the town of Ecatepec, Estado de México, in 2003, resulting in the apprehension of two individuals, who were sentenced to five years in prison for the manufacture and warehousing of counterfeit money.
 

The dismantling of a printing press dedicated to the counterfeiting of banknotes and other official documents in San Juan del Río, Querétaro, in which one person was apprehended.
