South Korea Faces Criticism for Crackdown on Leaflet Launchers William Gallo SEOUL, SOUTH KOREA - South Korean President Moon Jae-in, who began his career as a human rights lawyer, is coming under severe criticism for cracking down on activist groups calling for reform in North Korea. The Moon administration has carried out a broad campaign to prevent the organizations, mostly led by North Korean defectors, from floating balloons and bottles filled with propaganda leaflets into the North. The leaflets often criticize North Korea's human rights record or mock North Korean leader Kim Jong Un and are sometimes packaged with items of value, such as dollar bills or USB flash drives loaded with South Korean dramas. North Korea, which forbids access to the outside world, has complained bitterly about the leaflets. Last month North Korea demolished the de facto inter-Korean embassy just north of the border and threatened unspecified military action unless Seoul stopped the launches. The Moon government, which wants to improve ties with Pyongyang, says the crackdown is necessary to reduce military tensions. But activists say the government's response is unprecedented and may be fatal for many groups working on North Korean human rights. Fierce crackdown Over the past several weeks, South Korean authorities have raidedthe offices of non-governmental organizations, filed criminal complaints against the groups, and in some cases evensurveilled, briefly detained or physically blocked activists as they head to or from launch sites. Authorities have also moved to formally outlaw the launches and threatened to imprison violators forayear. Last week, South Korea's Unification Ministry revoked the NGO licenses of two of the most prominent leaflet campaign groups, complicating their ability to raise money. Officials have warned they will inspect 25 more groups, raising fears their licenses too will be cancelled. On Monday, a group of South Korean NGOs appealed to the United Nations for help against what they called an "unjustified and politically motivated" investigation. The actions, they said, risk "stifling...the entire North Korean human rights movement in South Korea." Global condemnation Many international rights groups have also condemned the crackdown with unusual bluntness. "Rather than kowtow to Kim JongUn'ssister, South Korea should be standing up for its own principles," saidPhil Robertson of Human Rights Watch. Last month, Kim JongUn'ssister, KimYoJong, called the leaflet launchers "human scum" and "mongrel dogs." Within hours, South Korea began pressuring the NGOs, raising accusations Moon was stifling free speech in order to placate the North. "I think President Moon and his people are so deep into this they don't see they're no longer making sense," saidRobertson. "Their actions are now violating the rights they spent their entire careers trying to build up." The U.N. Human Rights Office in Seoul also questioned the decision to revoke the NGO licenses, according to theDong-Anewspaper. .
