The leftists in the South Korean government are trying to legislate away a subsidy the North Korean defector groups receive to help their balloon launch campaign:
Government subsidies for anti-North Korea activists have emerged as a bone of contention at the National Assembly as rival parties are competing to get their respective human rights bills related to North Korea passed.
The subsidies allegedly have been used to fund the campaign of releasing balloons containing leaflets criticizing the Pyongyang leadership that are blown across the border.
The ruling Saenuri Party said Monday it favored keeping the subsidies for civic groups as a tool against North Korea, while the main opposition New Politics Alliance for Democracy (NPAD) argued that it will only anger the North.
The two parties failed to reach a compromise so the competing bills are now being deliberated at the National Assembly Foreign Affairs and Unification Committee. [Korea Times]
You can read more at the link, but ending the subsidies will not end the balloon launches. The defector groups will just have to raise more money privately to fund the launches.
