Australian Defense Minister Marise Payne says any military conflict on the Korean Peninsula will have catastrophic consequences for the whole world.

Payne issued the warning Friday during the so-called two-plus-two talks between South Korea and Australia in Seoul, which brought together the foreign and defense ministers of the two countries.

She also said Australia will actively implement sanctions on North Korea as required under UN Security Council resolutions.

Payne called on the international community to stand united in pressuring the North diplomatically, politically and economically so the regime in Pyongyang stops its unjustifiable behaviors, return to the dialogue table and participate in the respected procedures.

Australian Foreign Minister Julie Bishop echoed the warning. She also quoted Australian Prime Minister Malcolm Turnbull as saying that Australia is an ally of the U.S. and will support it in case any U.S. territory comes under attack.
