ガルフ・カルテル
Following the conflict with the Gulf Cartel, Los Zetas joined forces with the Beltrán Leyva Cartel (who was simultaneously separating from the Sinaloa Cartel) as well as the Juarez Cartel and Tijuana Cartel or Arellano Félix organization, to counteract the alliance of the Gulf Cartel, Sinaloa Cartel and La Familia Michoacana cartels. Since February 2010, the major cartels have aligned in two factions, one formed by the Juárez Cartel, Tijuana Cartel, Los Zetas and the Beltrán-Leyva Cartel; the other faction integrated by the Gulf Cartel, Sinaloa Cartel and La Familia Cartel.
