North tells S.Korea president to 'shut his mouth'

STORY: Kim Jong Un's sister had strong words for South Korea's president on Friday after he once again offered economic aid to Pyongyang - if they agreed to denuclearize.

State media on Friday reported that Kim Yo Jong said of the South's leader Yoon Suk-yeol, "It would have been more favorable for his image to shut his mouth, rather than talking nonsense, as he had nothing better to say."

Yoon first proposed what he himself has described as an "audacious" plan back in May.

He next brought it up on Wednesday at a news conference marking his first 100 days in office.

South Korea's Unification Ministry, which handles relations with the North, warned of further isolation and a worsening economic crisis.

"The Unification Ministry expresses strong regret over North Korea's denouncement of our president with a rude expression and distortion of our idea, instead of responding to our ‘audacious plan,’ and also showing their intention of continuing nuclear development today."

Kim Yo Jong has become a vocal critic of South Korea in recent years.

Her comments on Friday mark the first time a senior North Korean official has commented directly on Yoon's plan.

But while those comments are her harshest personal attack on Yoon to date, they weren't the first.

During a speech riddled with profanity earlier this month, she blamed the South for a COVID-19 outbreak in the North.

She also threatened "deadly retaliation" if it were to happen again.
