ARGENTINIAN President Carlos Menem has instructed Transport Secretary Armando Carnosa to transfer responsibility for the 20-year Subte metro operating concession to the city government. Detailed negotiations began on January 13, and by January 19 the federal government was understood to have accepted the city’s main demand - that 380m pesos of public funds due to be invested in the network over the remaining 16 years will be met by the federal treasury. Other issues to be resolved include this year’s 2m pesos operating subsidy - concessionaire Metrovías is not due to start making premium payments until 1999.
