North Korean leader Kim Jong Un’s sister has told South Korea’s president to “shut up” as he rejected an offer of economic aid in exchange for nuclear disarmament.

Kim Yo Jong, a member of North Korea’s politburohe also described South Korean President Yoon Suk-yeol as “really simple and still childish.”

“No one changes their fate for corn cake,” he added in a statement carried by state news agency KCNA.

South Korean Unification Minister Kwon Young-se called his comments “disrespectful and indecent.”

It is the first time a senior North Korean official has commented directly on what Yoon has called a “bold” plan.

He has said he is willing to provide gradual economic aid to North Korea if it ends nuclear weapons development and begins denuclearization.

But Ms Kim was scathing in her denunciation of the idea, saying of Mr Yoon: “It would have been more favorable for his image to keep his mouth shut, instead of talking nonsense, as he had nothing better to say.” .

North Korea fired two cruise missiles into the sea off its west coast Wednesday.

Last week, he threatened retaliation after an outbreak COVID-19[feminine] in the north, one claimed it was caused by southern activists dropping leaflets and other items from balloons.

Speaking to a large audience in Pyongyang on August 10, he said: “What matters is the fact that South Korean puppets are still throwing leaflets and dirty objects into our territory.

“The main culprit who seriously violated the security of our people inflicted pains and caused anxiety to millions of parents in our country, who had to endure all hardships to protect the lives of their precious children, were the despicable South – Koreans”.

He added: “We have wiped out the virus spread by South Korea’s scum. We must counter it forcefully. We have already considered various countermeasures, but our countermeasure must be deadly retaliation.”

The South’s offer of economic aid was first proposed in May, and Yoon spoke about it again on Wednesday as he marked his 100th day in office.

He has also pushed to increase his country’s military deterrence against North Korea, and Seoul has resumed long-suspended joint exercises with the United States, including major field exercises that begin next week.
