Pyongyang was told to abandoned its nuclear programme by assembled defence officials from the United States, South Korea and Japan.
A statement said: “Together they called upon North Korea to refrain from irresponsible provocations that aggravate regional tensions, and to walk away from its destructive and reckless path of development.”
The meeting saw American Staff General Joseph Dunford welcomed South Korea’s and Japan’s defence chiefs to US Pacific Command.
North Korea’s recent ballistic missile and nuclear test were discussed at the meeting.
The meeting comes ahead of a planned Asia tour by President Donald Trump which has been seen North Korea flood Seoul with propaganda.
Insults delivered to the South Korean capital by balloon branded the US President “mentally ill”.
President Trump will visit South Korea, Japan, China, Vietnam and the Philippines in a trip which has been viewed as highly provocative by Kim Jong-un.
Fears have been raised that Trump arriving in Seoul could spark a war on the Korean peninsula with tensions showing no sign of calming.
The Asia tour is a visible show of commitment to allies in the region, the Pentagon confirmed.
The tour was announced as a move to “confront the North Korean threat” in September.
The White House said: “The President’s engagements will strengthen the international resolve to confront the North Korean threat and ensure the complete, verifiable, and irreversible denuclearisation of the Korean Peninsula.”
The US has deployed nuclear bombers to the Pacific ahead of the Asia tour.
The nuclear-fitted B-2 bombers travelled to the region as US Defence Secretary James Mattis declared the US would not “accept North Korea as a nuclear power”.
