The government has concluded that the aviation law cannot be applied to block civic groups from distributing anti-North Korean propaganda leaflets near the inter-Korean border.
  
A Unification Ministry official said the ministry announced the conclusion on Thursday after having discussions with the Ministry of Land, Infrastructure and Transport.
 
The official said the giant balloons that civic groups use to send anti-Pyongyang leaflets across the border are not ultra-light flying machines that are designed to be controlled from the ground, which are subject to the nation's aviation law.
  
The official also brushed aside claims that it is possible to install a timer and a global positioning system to the balloons to make sure they land at an aimed site. The official explained that giant balloons are blown away by the wind and cannot be operated by people on the ground.
 
Pyongyang is pressuring Seoul, saying it will only agree to the second high-level talks and other inter-Korean dialogue once the anti-North leaflet campaign comes to an end.
