Newly elected Liberal Democratic Party President Taro Aso vowed Monday to do his utmost to solve problems that range from revitalizing the economy to improving the health care system.

In the evening, Aso appointed former Chief Cabinet Secretary Hiroyuki Hosoda as LDP secretary general, the party's No. 2 post.

Aso also gave former LDP policy chief Nobuteru Ishihara, one of his opponents in the presidential election, one of the party' two deputy secretary general posts. Motoo Hayashi, the current chairman of the National Public Safety Commission, was also appointed deputy secretary general.
