Los Zetas is Mexican.
 The cartel also has important areas of operation in Guatemala, where their operations are reported to have begun as early as 2008
The Netflix/Univision television series El Chapo depicts "Los Emes" as a semi-fictionalized version of Los Zetas that maintains an alliance with the Gulf Cartel and eventually wages a bloody gun battle with the Sinaloa Cartel for control of Nuevo Laredo
