Newly elected Director General of the International Atomic Energy Agency (IAEA) Yukiya Amano of Japan attends a meeting at Vienna's UN headquarters July 3, 2009. Japanese diplomat Amano, 62, was narrowly elected the next head of the U.N. atomic watchdog on Thursday and he vowed to tackle rich-poor tensions weakening the fight against the proliferation of nuclear weapons. He succeeds Nobel Peace laureate Mohamed ElBaradei, who retires in November after 12 turbulent years.
