Brazil's government may hold a tender in August for the construction of the 403-kilometer (250-mile) rail link between Rio de Janeiro and Sao Paulo, the ministry said in a statement.
Brazilian, South Korean, French and Italian companies have shown interest in building the rail link, the ministry said. French train maker Alstom made a preliminary proposal to build the link, according to a report by the Agencia Estado news service in April.
