At the 16th Political Bureau meeting of the Seventh Central Committee of the workers’ Party of Korea (WPK), North Korea’s top leader, Kim Jong Un, once again announced a personnel adjustment at the 16th Political Bureau meeting of the Seventh Central Committee of the workers’ party, the Korean Central News Agency reported. Two new members were added to the Standing Committee of the Politburo, and the core leadership returned to the “five regular” pattern once again. On the same day, the Korean Central News Agency published the “State Council decree” issued in the name of Kim Jong Un, announcing that “after the DPRK State Council has assessed and analyzed the cabinet’s economic organization work ability”, it decided to remove Jin cailong from the post of premier of the cabinet and appoint Kim teh Hun to take over the post. < p > < p > on April 11, 2019, the first session of the 14th Supreme People’s Congress of North Korea was opened, and Kim Choi long succeeded Park Fung Chu as the cabinet prime minister and became a member of the new leading group of the DPRK. Before that, Jin cailong served as chairman of the Party committee in cijiangdao, the concentration area of North Korea’s military industrial facilities. However, he was promoted directly from the local government to the Central Committee. Such a rapid promotion was the first time in the history of North Korea, which can be said to be an exceptional personnel arrangement. The analysis shows that under the pressure of sanctions, Jin cailong has made remarkable achievements in the economic aspect, which is affirmed by Jin Zhengen. His loyalty to the labor party also added points. It is worth mentioning that cijiang road is the birthplace of the “Jiangjie spirit” in the “suffering March” of North Korea in the 1990s through “self-reliance and overcoming economic difficulties”. From this point of view, he is also considered to be the best person to implement the “self-reliance” spirit emphasized by Kim Jong Un, and shoulder the heavy responsibility of revitalizing the North Korean economy. Zhao Fengxian, director of the North Korea Economic Research Center of IBK, once pointed out that at the stage when the North Korean economy is in trouble, it is necessary to import younger forces to ensure new impetus. However, he was transferred less than a year and a half after taking office. South Korean media believe that under the dual pressure of the new crown epidemic and the flood, the North Korean economy is unable to recover in the short term, and the “economic commander-in-chief” Jin cailong’s performance is not good enough to satisfy Kim Jong Un. According to South Korean media, Kim teh Hoon is 59 years old and relatively young among North Korean Party cadres. He is proficient in economy and has served successively as manager of Daan electric factory, chairman of cijiangdao people’s Committee and vice premier of cabinet. Like Jin cailong, he also made good achievements during his tenure in cijiangdao. Jin dehun and Li Bingzhe, vice chairman of the Military Commission of the CPC Central Committee, were jointly appointed members of the Standing Committee of the Political Bureau of the CPC Central Committee. In addition to the above-mentioned two “newcomers”, the “five standing committee” also includes: Kim Jong Un, chairman of the State Council of the Standing Committee of the Political Bureau of the Korean workers’ party, Cui Longhai, chairman of the Standing Committee of the Supreme People’s Congress and first vice chairman of the state Council, and park Fengzhu, vice chairman of the State Council. As the leading core and power symbol of North Korea, the increase in the number of standing committee members of the Political Bureau can be seen as continuing to consolidate the system of “ruling by the party”. Li Bingzhe is generally regarded as one of the “nuclear think tanks” with the highest status and the deepest seniority by North Korea experts. He joined the Standing Committee of the Politburo and entered the power center, which was not unexpected. According to South Korea’s central daily, Li Bingzhe was born in 1948, studied in the Soviet Union, served as the commander of the air force, and traveled to China and Russia. Later, he was responsible for directing the research and development of North Korea’s ballistic missiles, served as the first vice minister of the Ministry of military supplies industry, and often accompanied Kim Jong Un to inspect the test site. After the breakdown of the Hanoi talks between North Korea and the United States, the DPRK side strengthened the development of cutting-edge science and technology, continuously improved and optimized the performance of weapons, and repeatedly succeeded in test firing. As the commander in chief of strategic weapons research and development, Li Bingzhe was also promoted rapidly. At the end of last year, he served as vice chairman of the CPC Central Committee in charge of military supplies and a member of the Political Bureau. In April this year, he was elected as state councilor, and a month later, he “took” the post of vice chairman, who has been vacant since 2014. South Korean media pointed out that Li Bingzhe’s promotion this time indicates that North Korea will continue to focus on nuclear weapons and missiles, strengthen its national defense strength and enhance its ability to suppress and deter foreign countries in the future. In addition, park Taide, park Mingshun, Quan Guanghao and Jin Yongshuai were appointed ministers of the CPC Central Committee. Park Taide can be said to be restored to his original post this time, which is worthy of attention. He was removed from the post of vice chairman and Minister of the party in February this year because of “corruption”, and he once disappeared.
