 America Movil, the telecoms giant controlled by the family of Mexican billionaire Carlos Slim, said on Monday that one of its subsidiaries had been fined 1.3 billion pesos 69.53 million by Mexicos telecoms regulator. The regulator, the Federal Telecommunications Institute IFT, said in a statement that it fined the company for failing to share information about the availability of its telecom infrastructure, such as posts, with competitors. America Movil, which has long dominated Mexicos telecoms market, is required to open its infrastructure to industry rivals in order to promote competition.
