South Korean activists who send leaflets into North Korea could run into legal problems if they launch balloons carrying payloads that are too heavy, Seoul has warned, announcing plans to discuss the issue with activists as the DPRK continues retaliatory trash balloon launches.

The land ministry has informed relevant ministries and local governments that balloons with payloads exceeding 4.4 pounds (2 kg) could be considered ultra-light aerial vehicles under the Aviation Safety Act, the ministry confirmed to NK News.
