It marked North Korea's first response to the summit between President Moon Jae-in and his US counterpart Donald Trump. The DFRK is an agency affiliated with the ruling Workers' Party of Korea.

North Korea claimed that Moon is oblivious to the lessons of history as he is continuing to submit to the US while abusing the power granted to him by the candlelight vigils that were sparked by a corruption scandal involving his predecessor Park Geun-hye.

"That's why we Koreans never tolerated the traitors who sacrifice the nation's dignity and interests in pursuance of outsiders, being subservient to the US but dealt heavy blows on them," read its statement in English carried by the country's state news agency.

The DFRK claimed that genuine peace on the Korean Peninsula would start from Washington's withdrawal of its forces and weapons from South Korea, not from North Korea's nuclear dismantlement.

Moon took office in May with pledges to denuclearize North Korea, and seek dialogue and engagement with Pyongyang in parallel.

But the North has remained negative toward Moon's stance, saying there can be no dialogue if there are sanctions against it.

He and Trump agreed to leave the door for dialogue with North Korea open "under the right circumstances," during their first summit last week.

North Korea apparently toned down its criticism of the outcome of the summit as the Korean Central News Agency, which targets readers outside the country, did not fully carry the agency's statement.

But its radio station and main newspaper Rodong Sinmun, which targets North Koreans, released its outright condemnation.

The statement came on the 45th anniversary of a landmark inter-Korean agreement on peace and reconciliation.

In 1972, the two Koreas reached a joint statement outlining the three principles of independence, peace and national unity, a cornerstone for basic guidelines for inter-Korean talks.

Earlier in the day, Pyongyang fired a ballistic missile from its northwestern province near the border with China in an apparent show of its protest against the summit.

"North Korea should stop its nuclear and missile provocations, and move forward respecting inter-Korean agreements and improving relations between the two Koreas," an official at Seoul's unification ministry said.

Kim Yong-hyun, a professor at Dongguk University, said that North Korea's reaction seems to be aimed at taking the initiative by factoring in the possibility of dialogue. (Yonhap)
