-Tight grip across the border following Kim Jong Il's death
-Immediate execution of defectors
-Border patrol control under the NSA
It is a place where a great many North Koreans choose to defect, running the risk of being caught, repatriated, and executed.
Securing the northern border is more urgent than the border with the Panmunjeom - the border with South Korea. Kim Jong Un has clearly acknowledged the dangers of border crossings, and he is clearly aware that these crossing could eventually lead to the fall of the regime.
The 'Dear Leader' Kim Jong Il's sudden death in December of last year brought a tighter grip across the border.
Going even further,, Kim Jong Un ordered a "guilt by association" system, which is a collective execution system which aims to terminate the entire family of anyone who has attempted defection. Also, 20,000 additional soldiers were dispatched along the border region to tighten security in the area. Immediate execution of anyone caught attempting to defect was ordered as well. On December 31st, 3 men crossing the river in Hyesan, Yanggang province were executed by firing squad and a couple in their 40s attempting defection in Hoiryoung, Hamkyung Buk-do were executed as well. Clearly, there are unspeakable atrocities happening as the noose is tightened around the Chinese/North Korean border. .
Following the 100th anniversary of the Sun day, which celebrates the birth of Kim Il Sung, the authorities transferred border control from the Ministry of the People’s Armed Forces to the National Security Agency.
The transfer seems to be due to the continual leaking of information of sensitive issues, even after the death of Kim Jong Il. Previously, the PAF and NSA operated with co-responsibility. The PAF was charged with monitoring the border while the NSA undertook the tasks of tracking, arresting, and repatriating defectors. Now, however, all activities have been given over to the NSA.
Signal jamming around the border regions have also become more frequent in the era of Kim Jong Un. The regime spent $200 million importing German made signal detectors and frequency jammers to hamper the use of Chinese cell phones in North Korea. The large sum of money is about 3% of North Korea’s entire annual revenue of $5.7 billion.
The young Kim Jong Un may fear a coming tsunami of outside information, and it seems likely that the North Korean authorities will continue to build ever larger barriers to help push back this wave of information coming from the outside world.
