The powerful sister of North Korean leader Kim Jong Un on Thursday dismissed South Korean claims the North is removing some of its loudspeakers along the inter-Korean border, mocking the government in Seoul for clinging to hopes of renewed diplomacy between the war-divided rivals.

The powerful sister of the country's leader said North Korea has never taken down propaganda loudspeakers and will not do so, calling South Korea's belief that Pyongyang was responding to its peace overtures a "pipedream".

North Korean leader Kim Jong Un's sister has rebutted South Korea's claims that Pyongyang removed some of its propaganda-blasting loudspeakers along the border. North Korea has "never removed" the speakers and "are not willing to remove them", Kim Yo Jong said in a statement published by state media KCNA on Thursday.
