Six American citizens were detained on Friday while trying to launch plastic bottles filled with rice, miniature Bibles, one-dollar bills, and USB drives into the sea near North Korea, according to South Korean police.
Authorities said the group was stopped on the front-line island of Ganghwa (also spelled Gwanghwa), just before they attempted to send 1,600 bottles drifting toward North Korea’s coast using ocean currents. Police are now investigating the Americans for allegedly violating South Korea’s law concerning public safety and disaster management.
Due to privacy regulations, the officers — who spoke anonymously — did not release the detainees’ identities. The contents of the USB drives are still being examined.
The U.S. Embassy in Seoul has not released a statement on the matter.
Background on Border Activism
For years, anti-North Korea activists have used balloons and bottles to smuggle materials like leaflets, cash, and USB drives loaded with South Korean dramas and K-pop music into the North. These activities were outlawed between 2021 and 2023 amid concerns they could escalate tensions with Pyongyang.
North Korea has strongly objected to such campaigns, often responding with threats and countermeasures. Last year, in retaliation, the North launched its own balloons filled with garbage into South Korea, littering areas including the presidential compound.
In 2023, South Korea’s Constitutional Court overturned the leaflet ban, calling it an unconstitutional restriction on free speech. However, the newly elected government under liberal President Lee Jae Myung is now cracking down on such civilian operations using other legal measures tied to public safety.
Earlier this month, on June 14, another activist was arrested for launching balloons from the same Ganghwa Island location.
Political Context
President Lee, who took office in early June, has pledged to revive peace talks with North Korea and reduce military tensions on the peninsula. As part of that effort, his administration recently halted the loudspeaker broadcasts that had been aimed at North Korean troops along the border. North Korea has since stopped its own broadcasts as well.
Despite these gestures, it remains unclear whether Pyongyang will reciprocate. North Korea previously declared it would no longer seek peaceful reunification with the South and has cut off official communications since diplomacy collapsed in 2019.
Friday’s incident underscores the continuing challenges in managing activism, diplomacy, and national security in one of the world’s most sensitive border regions.
