Kim Yo Jong, the influential sister of North Korean leader Kim Jong Un, said Monday that Pyongyang had "no interest" in efforts by Seoul to improve relations.

For the first time since South Korea’s new president assumed office, Pyongyang explicitly nixed the Lee administration’s pro-dialogue approach to North Korea.

The powerful sister of North Korean leader Kim Jong Un dismissed the US's intent to resume diplomacy on North Korea’s denuclearisation, as she urged Washington to accept her country as a nuclear weapons state and find a new approach to restart talks.
