Incoming International Monetary Fund Managing Director Rodrigo Rato said this week that during his five-year mandate as head of the institution, he will work toward fulfilling the interests of its 184 member countries while giving special attention to poor nations. "The position of managing director of this institution requires me to work in the interest of all 184 member countries, with particular attention to those who have the greatest difficulties and lower income levels," Rato said in his first news conference in Washington after being chosen as the IMF chief last week. He is scheduled to officially assume the new position early next month.
