Former Prime Minister Naoto Kan has urged Australia to help wean the world off uranium instead of increasing its already considerable exports of the radioactive metal, local media reported over the weekend.

Kan, who was prime minister during the Fukushima nuclear disaster in 2011, is on a weeklong visit to Australia.

"I hope that Australia can be exporting not uranium . . . but electricity created through renewable sources," Kan was quoted Saturday as saying by the Australia Broadcasting Corp.
