What instructions did Defense Minister Kang Shin-chul give in response to the MDL mine issue?

The MDL has served as the de facto border under the Armistice Agreement for over 70 years.
There are concerns that the North Korean military has successfully established several box minefields south of the line that are undetectable by mine detectors.
Originally, if North Korea moved south of the demarcation line, warning shots should have been fired to repel them, but I worry that this principle of response has not been properly upheld under this administration.
As a result, they have successfully created minefields in several locations under the foolish and powerless gaze of our military.
If we fail to handle this situation properly, we will face a situation where our actual territory under effective control retreats southward.
The government and the President surely swore to protect our nation's territory upon taking office. I am curious whether they are just sitting idly by and letting this happen, or if Kang Shin-chul has taken any action.
This is a matter of whether we will protect the safety of our service members and fulfill our constitutional duties.
