Australia To Japan: Stop All Whaling Or Face International Legal Challenge (VIDEO)

Australia is turning up the heat on Japan's whaling practices. Australian Prime Minister Kevin Rudd announced that unless Japan reduces all whaling activities to "zero" by November 2010, it will face an international legal challenge, Reuters reported.

Japanese Foreign Minister Katsuya Okada responded to the ultimatum at a press conference in Tokyo.

"We understand that the current Australian government in its manifesto opposes whaling for research purposes," Okada said. "With that in mind, we would like to have a calm and substantial discussion."
