Kerry en route to Japan seeking help in reining in N. Korea

US Secretary of State John Kerry was en route to Japan on Sunday, the last stop on an Asian tour aimed at reining North Korea's nuclear ambitions.

Kerry met China's top leaders on Saturday in a bid to persuade them to push reclusive North Korea, whose sole main ally is Beijing, to scale back its belligerence and return to nuclear talks after weeks of threats of nuclear attacks on the United States and South Korea. (Reuters)
