The powerful sister of North Korean leader Kim Jong Un said on Monday (April 6, 2026) that the regret expressed by Seoul over a January drone incursion into the North is “wise behaviour”.
Earlier in the day, South Korean President Lee Jae Myung expressed regret to Pyongyang over drones sent into the nuclear-armed North earlier this year, actions he called “irresponsible”.
“The ROK president personally expressed regret and talked about a measure for preventing recurrence. Our government appreciated it as very fortunate and wise behaviour for its own sake,” Kim Yo Jong said in a statement carried by the official Korean Central News Agency, using the official name of South Korea.
Seoul initially denied any official role in the January drone incursion — with authorities suggesting it was the work of civilians — but Mr. Lee said a probe had revealed government officials had been involved.
The North warned in February of a “terrible response” if it detects more drones crossing the border from the South, prompting Seoul to investigate the claims.
Pyongyang said it downed a drone carrying “surveillance equipment” in early January.
Photos released by state media showed the wreckage of a winged craft scattered across the ground alongside grey and blue components that allegedly included cameras.
“It has been confirmed that a National Intelligence Service official and an active-duty soldier were involved,” Mr. Lee told a cabinet meeting.
“We express regret to the North over the unnecessary military tensions caused by the irresponsible and reckless actions of some individuals,” he said.
He added that South Korea’s constitution bans private individuals from conducting acts that could “provoke the North”.
“Such actions, even when deemed necessary for national strategy, must be approached with extreme caution,” he said.
Ms. Kim Yo Jong said her brother had taken Mr. Lee’s remark “as a manifestation of a frank and broad-minded man’s attitude”, but warned Seoul to “stop any reckless provocation against the DPRK and refrain from any attempt at contact”, using the initials of the North’s official name.
“The ROK side should be mindful that it will be forced to pay a price… if such a provocation as violating the inalienable sovereignty of our state occurs again,” she warned.
‘Most hostile state’
Mr. Lee has sought to repair ties with North Korea since taking office last year, criticising his predecessor for allegedly sending drones to scatter propaganda over Pyongyang.
His repeated overtures, however, have gone unanswered by the North.
Former South Korean president Yoon Suk Yeol is standing trial over charges that his administration sent drones into the North to provoke a backlash and create a pretext for declaring military rule.
Yoon was impeached and ousted from office in April last year and has been sentenced to life in prison over his declaration of martial law.
Mr. Lee’s expression of regret follows North Korean leader Mr. Kim Jong Un’s labelling of Seoul as the “most hostile state” in a policy address in March in which he vowed to “thoroughly reject and disregard it”.
North Korea’s leader also reaffirmed his commitment to maintaining the country’s nuclear arsenal, describing it as an “irreversible course”.
During Yoon’s presidency, relations between Seoul and Pyongyang hit rock bottom, with the North sending balloons filled with garbage, including animal manure, in response to propaganda leaflets sent northward by South Korea-based activists, many of them North Korean defectors.
The two Koreas technically remain at war, as the 1950–53 conflict ended in an armistice rather than a peace treaty, and both enforce mandatory military service for men.
