The Lee Myung Bak group has blocked economic cooperation and exchange between the north and the south, getting frantic in confrontation with the DPRK after the "Cheonan" warship sinking case. Consequently, enterprises of south Korea are going bankrupt en masse with the scale of damage increasing day by day.

Nevertheless, the puppet "government" authorities have refused to compensate for damage while talking about "dangerous investment."

Enraged at this attitude, at least 20 businesses, including those involved in investment on tourism in Mt. Kumgang, set out to take legal actions against the "government."

Some enterprises involved in the south-north economic cooperation had separately sued for damage so far, but it is the first time the group protest has been made after the "May 24 step".
