South Korea's new administration cracks down on balloon activists targeting North Korea, leading to legal challenges and halted operations.
By Ju-min Park
POCHEON, South Korea (Reuters) -The equipment activist Lee Min-bok uses to send balloons laden with anti-Kim Jong Un leaflets across the border from South Korea unto the North has been gathering dust and cobwebs for months.
When it became clear that centre-left politician Lee Jae Myung was on track to win the June presidential election, Lee Min-bok was among several South Korea-based activists who stopped their missions, anticipating a crackdown by the new, pro-engagement administration.
Lee Jae Myung, a former human rights lawyer, is pushing to ease tensions with Pyongyang and last month said activists should be "severely punished" if they continue the balloon operations that anger North Korea.
"I've been doing it quietly and what's wrong with that? Provoking North Korea? No way," 67-year-old Lee Min-bok told Reuters as he stood next to a rusting truck equipped with a hydrogen tank for filling balloons.
"But realistically, look how serious it is right now. Police are out there and if I move, everything will be reported."
For years, police have monitored Lee from the home next door - one plainclothes officer told Reuters they are there to protect him from potential North Korean threats - but instead of checking weather reports for ideal balloon launching conditions, Lee now spends his days writing online posts criticising the South Korean government.
CALLS TO ACTIVISTS
The activists, many of whom are North Korean defectors like Lee, are used to being at the centre of geopolitical tensions.
An attempt by a previous liberal president to ban the balloon launches was struck down as unconstitutional. And last year, North Korea began launching waves of its own balloons into the South, some carrying garbage and excrement.
Lee, who took office on June 4, has promised to improve relations with the nuclear-armed North, saying tensions with Pyongyang have had a real negative economic impact. He has urged diplomacy and dialogue and his administration has also suspended anti-North Korea loudspeaker broadcasts along the border.
North Korean leader Kim Jong Un, however, last year abandoned a goal of unification with the South and has shown little openness to diplomacy.
After Lee ordered measures to stop leaflet launches, officials and police discussed plans including deploying police to border regions to preempt launches, and punishing the activists by using regulations such as aviation safety laws, according to the Unification Ministry that handles inter-Korea affairs.
Several groups in the South regularly send balloons to the North carrying leaflets, bibles, food, money, and various media.
In the past year, police have investigated about 72 cases of anti-North leaflet activities and sent 13 to prosecutors, another police official said. They are still looking into 23 cases, the official added.
Police are also investigating six Americans who attempted to deliver around 1,300 plastic bottles filled with rice, dollar notes and Bibles to North Korea.
"Fear is spreading. The mood is bloody intense," said another North Korean defector-turned-activist who had secretly flown balloons once or twice a month for more than a decade.
The activist said he had paused the launches this spring when polls showed Lee was likely to win the election.
"I get calls from the government recently that apparently want to check in, to see whether I am going to send the balloons or not," said the Seoul-based activist, who declined to be named for fear of reprisals.
Choi Sung-yong, leader of the Abductees' Family Union who works to bring home South Koreans abducted by North Korea, said his group had decided to suspend the balloon launches after receiving calls from new government officials.
Chung Dong-young, the Unification Minister nominee, said last month he rang Choi and thanked him for reconsidering the balloon launches which Chung described "a catalyst to confrontation and hostilities" between the two Koreas.
'RIGHT BALANCE'
North Korean officials have labeled leaflet activists in South Korea "human scum" and in 2020 demolished an inter-Korean liaison office during a spat over leaflets. In 2022, they claimed the balloons could carry the coronavirus.
The Lee administration's moves have been welcomed by some residents who have said the launches put them at risk.
"I feel much more comfortable and hopeful… People couldn’t sleep," said Park Hae-yeon, 65, a farmer in Paju whose family runs a restaurant near the border. "Now I am hearing leaflets not being distributed, I see a sign of hope."
James Heenan, who represents the U.N. High Commissioner for Human Rights in Seoul, told Reuters that leaflet operations are a matter of free expression that need to be balanced with legitimate national security concerns.
"We hope the right balance will be struck," he said, noting that previous punishments were overly harsh.

The South Korean government has ordered measures to stop leaflet launches, including deploying police to border regions and punishing activists through regulations.
Lee Min-bok is a 67-year-old activist known for sending balloons with anti-Kim Jong Un leaflets into North Korea. He has paused his activities due to the current political climate.
President Lee Jae Myung has expressed a desire to improve relations with North Korea and stated that activists should be 'severely punished' if they continue balloon operations.
North Korean officials have labeled South Korean leaflet activists as 'human scum' and have previously taken aggressive actions, such as demolishing an inter-Korean liaison office.
Some residents have welcomed the government's crackdown on balloon launches, stating it has made them feel more comfortable and hopeful, as the launches previously caused anxiety.
