South Korea President Moon Jae-in on Tuesday repeated a call for a formal end to the Korean War in an address to the UN General Assembly and proposed that the two Koreas with the US, or with the US and China, make such a declaration.

The two Koreas are still technically at war after their 1950-1953 conflict ended in a ceasefire rather than a peace treaty.

“Nothing will change as long as the political circumstances around the DPRK remains unchanged and the US hostile policy is not shifted, although the termination of the war is declared hundreds of times,” Ri said on KCNA, using North Korea’s official name, the Democratic People’s Republic of Korea.

“The US withdrawal of its double-standards and hostile policy is the top priority in stabilising the situation of the Korean peninsula and ensuring peace on it.”

On Tuesday, US President Joe Biden addressed the UN assembly and said the US wants “sustained diplomacy” to resolve the crisis surrounding North Korea’s nuclear and ballistic missile programmes.

North Korea has rejected US overtures to engage in dialogue and the head of the UN atomic watchdog said this week that Pyongyang’s nuclear programme is going “full steam ahead”.

North Korea and South Korea test-fired ballistic missiles last week, the latest volley in an arms race in which both nations have developed increasingly sophisticated weapons amid fruitless efforts to start talks to defuse tensions.
