Australian Prime Minister Kevin Rudd called Friday for "harsh" sanctions against North Korea for conducting nuclear tests, saying the communist nation will only respond to a unified show of strength by the world.
Rudd told the opening of a regional security conference that the international community, through the UN Security Council, must act tough toward North Korea since verbal statements of condemnation have been ineffective.
"If I thought there was something else in there that would work I would embrace that. But I believe strength and resolve is what is necessary to command the attention and respect" of North Korea, Rudd said.
They "respond only to a unified demonstration of strength," he told the Shangri-La Dialogue, an annual gathering of the region's defense ministers organized by the London-based International Institute for Strategic Studies think tank.
