Carvalho said bets would be taken on foreign races to create a fund to develop competitions in Portugal and to breed horses in the country while the tracks were being built.
He estimates that bets on horse races could generate up to €300 million a year and create about 6,000 jobs.
Ricardo Carvalho added that although Portugal has noble breeds of horses, such as the Lusitano, there are no race horses so they would have to work with English pure-breeds, the traditional race horses.
