ARGENTINA-US-ECONOMY-DEBT-KIRCHNER -

Argentina's Presient Cristina Fernandez de Kirchner waves to supporters after a ceremony at the government house on July 31, 2014 in Buenos Aires, Argentina. Argentina blamed the United States Thursday for the legal battle that forced it to miss a debt payment and -- despite ratings agencies' declarations to the contrary -- denied being in default.
