Radio México Internacional is a Mexican government-run radio service based in Mexico City. It broadcast as a shortwave radio station with the broadcast callsign XERMX-OC from 1969 to 2004, and was relaunched as an Internet-only radio service in 2011. Since 1983 it has been under the control of the Instituto Mexicano de la Radio (IMER). The -OC suffix is from , Spanish for "short wave", equivalent to the -SW suffix in Canada (with none being used at all on U.S. shortwave stations).
Federal shortwave broadcasting in Mexico goes back to at least 1934, when the Secretariat of Foreign Affairs (SRE) started XECR. It was discontinued in 1937 when the government of Lázaro Cárdenas began shortwave station XEXA through the Autonomous Department of Press and Publicity (Spanish: Departamento Autónomo de Prensa y Publicidad, DAPP). XEXA continued into the 1940s.
In 1968, Luis Echeverría, then Secretary of the Interior (Spanish: Secretaría de Gobernación), ordered Notimex to create a new shortwave station. The Secretariat of Communications and Transportation (SCT) allocated a set of five frequencies to be used at various times of the day: 5985 kHz in the 50-meter band; 9705 kHz in 31 meters; 11700 kHz in 25 meters; 15430 kHz in 19 meters; and 17765 kHz in 16 meters.
XERMX-OC began broadcasting on 1 September 1969. It was taken over by the Instituto Mexicano de la Radio (IMER) in 1983, and ceased broadcasting on 1 June 2004. It had 10,000 watt transmitters.
