(Telecompaper) America Movil has announced the termination of its deal to acquire 99.3 percent of Telefonica's Movistar El Salvador unit due to the strict anti-trust conditions imposed by the country's competition watchdog. The decision is by mutual agreement and comes "after careful consideration by both parties of the conditions to obtaining regulatory approval established by the Superintendencia de Competencia in their recent ruling on the proposed transaction," said the Mexican telecommunications giant in a statement.
