Argentina’s political scene experienced remarkable changes due to the failure of the Front for Victory （Frente para la Victoria） in mid-term parliamentary election. To reinforce the government administrative power，the Congress approved a number of law bills presented by the government before new senators took office. During 2009，impacts of international financial crisis turned to the worse and agricultural output suffered huge losses caused by natural disasters. The government of Cristina Fernandez adopted various measures to stimulate the national economy and signs of recovery emerged in the second half of the year. The society tended to stabilize but successive outbreaks of infectious diseases severely affected people’s livelihood. No significant steps were taken on the diplomatic frontier by the government and relations with other countries remained unchanged except with Honduras.
