South Korea and the United States reached an agreement on the return of 12 U.S. military bases to South Korea at a recent meeting of the Joint Committee on the status of U.S. forces in South Korea. So far, only 12 of South Korea’s 80 U.S. military bases have yet to be recovered. According to foreign media reports, South Korean people are strongly dissatisfied with the heavy metal pollution in the newly returned military bases. At present, South Korea and the United States have not yet reached an agreement on the cost of base management. < / P > < p > according to the latest agreement, the US military bases in South Korea to be recovered by South Korea include five in Longshan District of Seoul, one in Central District of Seoul, three in Gyeonggi do, and three in Daegu City, gyeongshang North Road and Jiangyuan road. The total area of these 12 military bases is 1.465 million square meters, equivalent to half the area of Seoul’s Yu island. < / P > < p > it is reported that among the bases transferred to South Korea this time, Longshan base, the former headquarters of the US military in South Korea, is located in the center of Seoul. The base has always been the headquarters of the US military in South Korea, and it was not transferred to Humphrey battalion in pingze until September 2018. It is reported that this is the first time that South Korea and the United States resumed part of the land of the Longshan U.S. military base in 2002 and 2004, respectively, according to the joint land management plan and the Longshan base relocation plan. South Korean officials pointed out that most of the bases will be demolished after they are recovered, and the land will be used to build apartments, infectious disease hospitals and Longshan park. < / P > < p > according to Yonhap, the inspection results of the South Korean military inspection team on 12 bases show that 11 bases are seriously polluted by heavy metals and oil. South Korean government officials revealed that the two sides have reached a consensus on the return of the 12 facilities, but there are still differences on who should bear the cost of base management. < / P > < p > Yonhap said that, like the four US bases returned in December last year, the South Korean government will bear the cost of governance first, and the specific issue of sharing will be left to be discussed with the US side in the future. The two sides will also discuss issues such as clarifying the responsibility for pollution purification, strengthening the environmental management of the bases in use, formulating pollution management standards and joint investigation procedures in case of environmental accidents. The South Korean government will continue to consult with the United States with the state affairs adjustment office as the center and the coordination of various departments. < / P > < p > it is reported that South Korea intends to use this governance fee as a bargaining chip for US military spending in South Korea, but the South Korean government denies this statement. South Korean military experts pointed out that this environmental treatment fee is not a small sum. In order to deal with the pollution problem of three US military bases recovered last year, the South Korean government spent 98 billion won. If calculated according to this amount, South Korea may need to pay at least 349.4 billion won for the later governance of the 12 bases. < / P > < p > Cui Zhangyuan, the first director of the state affairs adjustment Office of South Korea’s Tsing wa Tai, said that the government will comprehensively consider the relocation plan of the US military base in South Korea, the regional development plans of various local governments, as well as the negotiation with the US side and other factors, and strive to recover all the land of the Longshan base and other US military bases in South Korea as soon as possible. Analysts pointed out that the U.S. agreement to return some bases does not mean that the U.S. troops in South Korea really want to withdraw from South Korea. The U.S. consideration between advance and retreat is its own interests. < / P > < p > in recent years, the US military has continuously strengthened its military deployment in the Asia Pacific region. The US Navy recently announced that in order to increase its military strength in the Asia Pacific region, the US military will reorganize the “first fleet”. The fleet will carry out important tasks in the Asia Pacific region, the report said. The US military in South Korea closed some bases mainly to save money. The United States has previously said that after closing some bases, it will gradually move the bases to the south of South Korea, where the geographical location is superior and the missile threat is smaller. < / P > < p > judging from the trend of the US military, the US military stationed in South Korea is indeed reducing its establishment and unnecessary consumption, but the most critical “sad” system and the air force base capable of deploying F-22 fighters and B-52 strategic bombers are still firmly in the hands of the US military. Some experts pointed out that at present, the U.S. military still has 12 bases in South Korea, which is expected to be reduced to 5-8 eventually. The U.S. military is likely to send additional F-22, F-35 and other stealth fighters to these bases, and equip them with new medium range ballistic missiles, land-based “Aegis” air defense system, etc. In the future, the United States will also build Japan into a “second echelon strike position”, and together with South Korea, form a US western Pacific strike position. < / P > < p > for the United States, closing several bases in South Korea is not a big problem, but for South Korea, the significance is naturally different. Two years ago, the president of Korea, moon Jae in the Ming Dynasty, made clear that he wanted to recover the wartime command in 2023, so that the Korean army could be truly independent and that all the US troops in South Korea should leave the country. In addition, the United States has always regarded the overseas garrison as an important tool to promote hegemony. The U.S. garrison in South Korea is basically not subject to local laws, and often acts recklessly, causing strong protests from the South Korean people. It can be said that the return of several bases by the United States, to a certain extent, is also an expedient measure to pacify the dissatisfaction of South Korean society and temporarily stabilize the blue house.
