New tourist boom in Argentina.
Tourism is one of the fastest growing industries in the world and Argentina is a country where the tourism sector is booming. At the moment,seven out of ten visitors to the country stay in the capital,Buenos Aires.However,the Tourism Secretary, Santiago Lombardi, is hoping to interest tourists in the country's other attractions,such as the waterfalls of Iguazu and the spectacular wildlife and landscape of Patagonia.
    Buenos Aires is currently attracting millions of dollars of investment in the tourist sector.Between 1996 and 1999,hotel groups invested about $ 800 m in building projects.This figure doubled to more than $1.6 bn between 2002 and 2006.This year alone they are building 26 new hotels.This includes a new 600 -room luxury Hilton hotel and shopping complex in Puerto Madero,an area of the city which was an industrial wasteland only few years ago.
   Buenos Aires is also developing its resources as a center for business conventions.British Airways now operates direct non-stop flights between London and Buenos Aires 5 days a week.Accordingly to the President of Congresos Internacionales,a Buenos Aires -based conference organizer,the capital receives between sixty and seventy conferences a year.It estimates annual growth at about 15%.
