Australia and Japan on Wednesday reaffirmed their commitment to pressuring North Korea to abandon its nuclear weapons program and enforcing sanctions on Pyongyang.
Australian Foreign Minister Marise Payne said Australia and Japan are committed to working closely with allies and partners to ensure North Korea is pressured to end its nuclear and missile programs.
"We need to see real steps to complete, verifiable irreversible denuclearization" of the Korean Peninsula, Payne told reporters.
Payne and Kono had discussed sanctions enforcement with the United State at last month's UN General Assembly in New York.
Iwaya said the "international community must remain united" to achieve the dismantling of North Korea's weapons of mass destruction.
"No country wishes for a new cold war," Kono said.
