Espionage against South

The biggest miscalculation made by North Korea in South Korea’s operations in the 1980s was sending relief supplies for floods to South Korea. The intelligence officers sent to the south allegedly reported that the Chon Doo-hwan administration would never receive the relief supplies. However, the South said they would receive the relief supplies. So the North struggled to collect various supplies. As a result, Kim Jung-rin, who was in charge of espionage against South, was relieved of his responsibilities and again was humiliated for six months working on the farm. (Ibid.)

Government Building No.3 is responsible for espionage against South in North Korea. Kim Jung-rin was in charge of espionage against South in the 1980s. Kim Jung-rin also failed earlier in Rangoon bombing.
Kim Jung-rin also commanded the infiltration of the south during the Gwangju Democratization Movement in 1980.

Kim Jung-rin issued an emergency decree to all units of Government building No. 3 after the intelligence network sent to South Korea was told that the Gwangju democratization movement had been heard. At that time, Kim Jung-rin was the South Secretary in charge of South Craft. Immediately after the outbreak of the Gwangju Democratization Movement, five or six days later, Kim Il-sung and Kim Jong-Il finally submitted a report on the final situation.
The report defines “the nature of the Gwangju case as a collision between workers, peasants, urban small citizens, a conscientious intelligent class and a military force backed by a buying capitalist.” This would create a favorable situation for the Republic if the conflicts were amplified. ” He added that “ it is a problem that riots are limited to Gwangju, ” he said.“If we spread riots throughout South Korea, there would be a decisive opportunity for South Korea’s business. ” tied.
According to Im Manbok, an instructor at Division 6 of the South Communications Department, Kim Jung-rin issued an emergency waiting order to all South Intelligence agents when the situation broke out. However, it was only 26 days before the Chongjin Combat Liaison Office, also known as Government Building No.3, received an order to infiltrate south from the top. The Kiyotsu liaison office, the largest south liaison office in North Korea, has 1,200 professional workers alone.
Dozens of elite operatives were ordered to prepare speedboats for infiltration into South Korea. The speedboat is a Japanese-made boat fitted with a tank engine, and has a maximum speed of 60 knots. However, because of the will, the operatives loading weapons on the fastboat were suddenly ordered to stop the sortie. It is true that Kim Jung-rin missed the time to respond, but it would be correct to see that the martial law’s suppression of the Gwangju province was faster than North Korea had expected.
When the Gwangju Democratization Movement took place, Lee He-Sup, the son of Lee Dong-ho, the first Deputy Director of the United Front at the time, made espionage against South publicity leaflets to support the Gwangju Democratization Movement without sleeplessness for weeks. And sprayed. At that time he was a coach of the 101st liaison office, which reports directly to Government building No.3. The No. 101 liaison office is printing all printed materials, including fake dollars, as well as advertising leaflets for southern crafts. (Ibid.)

According to the following testimony, North Korea’s South Korea project had a plan to break the dam and submerge Seoul.

Spring of 1985. A serious meeting was held at the People’s Armed Forces Ministry. The participants were Kim Il Sung and Kim Jong Il’s parents, and the top Korean leaders such as Oh Kun-yol and Oh Jin Woo. According to Wu Kangling, the destruction of the Kumgansan Dam will make Seoul completely submerged. Of course, North Korea also knew that the Kumgansan Dam alone could not submerge Seoul. Civil engineering calculations show that the water level of seven to ten meters is insufficient to submerge Seoul with the Kumgansan Dam alone.
Therefore, we started the construction of Abyung-dong Nisari Canal. There is a river on the shores of Gangwon-do that runs to the Donghae / Sea of ​​Japan. The distance to Kumgansan Dam is about 20 ri (about 8 km). Therefore, North Korea decided to draw the river channel to the Kumgansan Dam in order to flood Seoul. Initially, one division was mobilized. However, the progress of the canal construction, which began in 1985, was not very bleak. Therefore, Kim Jong Il invested two engineer divisions, which had been mobilized for the construction of the Sari-in Kali Fertilizer Factory, into the construction of the Kumgansan Dam. At the time, the lead of the project was General Lim Unsuk, Deputy Commander of the First Group Army. He is currently Commander Pyongyang Maolan. (Ibid.)

In addition to large-scale dam-breaking events, North Korea’s espionage against South activities have extended to the creation of propaganda music for psychological warfare.

There are cassette tapes in the north. There are roughly two types. One is a tape produced by Pochonbo Electronic Orchestra, which plays songs such as “whistling” and “smile of love” and the theme song of a movie using an electronic organ. Orthodox but not very popular.
The other is a tape made by Chirposan Electronic Orchestra. However, this tape is a special tape made by the Government Building No.3 in charge of southern construction, and was not made for northern residents.
It is a tape made for a southern psychological warfare to encourage southern soldiers to go north on truce lines. Therefore, all songs are from South Korea, and only the lyrics have been replaced with songs that praise Kim Il Sung and North Korea. So it’s much better than Pochonbo tape, but it’s not easily available. As a result, South Korean tapes are becoming increasingly popular. That is why the northern elite compete for the southern tape. There have been countless cases of social security officers (police) caught while listening to tapes from South Korea. (Kan Myong-do, Top Secret of North Korea)
