Recently, South Korean media have reported that South Korean citizen groups have questioned and dissatisfied with the biochemical laboratory operated by the US military in South Korea, calling on the government to investigate the relevant situation, disclose information and close the laboratory. The international community is also highly concerned about the biological militarization activities of the United States outside its territory, calling on the United States to abide by relevant international conventions and improve transparency. < / P > < p > in 2015, a military research institute in Utah sent active anthrax samples to Wushan Air Force Base of South Korea in the form of ordinary package through an American Express Company. After the incident was exposed by Korean national daily and other media, the U.S. military’s biological and chemical weapons research program in South Korea since June 2013, namely the “Jupiter” program, was made public. < / P > < p > according to the information released by the Ministry of defense of the Republic of Korea at the end of 2015, the US military sent anthrax specimens to the Republic of Korea several times from 2009 to 2015, conducted 16 experiments, and introduced Yersinia pestis once in 2015. South Korean military experts said the U.S. military had set up a anthrax laboratory in the U.S. military base in South Korea as early as September 1998, Han Minzu Daily reported. In addition to Bacillus anthracis, there is a highly toxic substance called botulinum toxin type A in the samples involved in the project, which is 100000 times more toxic than Bacillus anthracis. < / P > < p > according to South Korea’s unified news report, after the exposure of the “Jupiter” plan, the US military has not disclosed the real situation of biochemical weapons experiments in the US military base in South Korea. The US military has operated chemical and biological weapons laboratories at least at four US bases in Seoul, Busan, Wushan and Qunshan. In December 2019, the US military held a briefing meeting at the eighth wharf of Busan Port due to the suspected delivery of biochemical weapons and bacteria, and disclosed the follow-up plan of “Jupiter”, code named “Centaur”. < p > < p > in March this year, South Korea’s jtbc television station disclosed the news that American research institutions operating the “Centaur” project were publicly recruiting laboratory personnel. According to reports, the agency released work locations including Seoul, Busan, Daegu, dongdouchuan, Zhenhai, woguan and other places, indicating that the number of us biochemical laboratories in South Korea is still increasing. Although the U.S. military in South Korea argued that the “Centaur” project was only operated in the eighth dock base of Pusan port and the “Humphrey camp” of pingze base, it did not explain the public recruitment of laboratory personnel and the new work locations. According to the US military plan, the “Centaur” project will end in September this year, and then be transformed into a new “IEM integrated early warning mechanism”. The US biochemical project in South Korea will continue. < / P > < p > according to the Busan daily, the South Korean people expressed great concern about the secret biochemical experiments carried out by the US military in South Korea. The public response Committee of Busan expelling US bacteriological forces said that thousands of people would be gathered to report Robert Abrams, commander of US forces in South Korea, to the South Korean prosecutor’s office for the second time before September this year. The South Korean people strongly urged the South Korean Congress to discuss the issue of closing the US biochemical weapons laboratory in South Korea. < / P > < p > biochemical activities not only in South Korea, but also in many other countries in the United States have also aroused widespread doubts and opposition. According to the Russian news agency, the US military has participated in the construction of a number of biological laboratories in Ukraine, Georgia and other countries. According to the disclosure of foreign media, the relevant laboratories are in fact completely under the leadership of the US side, and are instructed by units under the US Department of defense to study dangerous diseases for specific populations, and then to study many research projects banned in the US. < / P > < p > according to the previous report of the Russian news agency, the Ministry of health of Ukraine said that from 2005 to 2014, the US infrastructure construction company bolek wich, with the consent of the US Department of defense, successively built eight laboratories in Lvov state, outer Carpathian region and Crimea region of Ukraine, and these laboratories stored very dangerous microbial infection samples. Relevant departments of the US Department of defense have provided technical support for the construction of some laboratories and participated in the modernization of some laboratories. The Russian news agency quoted the Ukrainian Ministry of health as saying that the relevant contracts show that the technology, pathogens and scientific knowledge possessed by these laboratories may be used to develop biological weapons. It is understood that many local people strongly demand the closure of relevant laboratories. < / P > < p > according to a research report on the official website of the Russian Ministry of defense, the US Army has funded the establishment of more than 200 biological laboratories in many countries in the world and commissioned them to carry out research on viruses and their transmission media. These laboratories are distributed in Russia’s neighboring countries, Southeast Asia, South Asia, Africa and other places. The report shows that although the US military claims that the purpose of setting up biological laboratories overseas is to conduct biological monitoring, provide assistance to developing countries, and develop means and methods to prevent biological attacks, this is not the case. Its direct purpose is to develop technical means for the delivery of biological weapons, which violates the relevant provisions of the Convention on the prohibition of biological weapons. < / P > < p > Bulgaria investigated dilyana getanzieva’s report in 2018, saying: “the US military often produces lethal viruses, bacteria and toxins overseas, which directly violates the Convention. Hundreds of thousands of people are unknowingly and systematically exposed to dangerous pathogens and other incurable diseases. These U.S. biological laboratories are funded by a $2.1 billion biological collaboration program of the U.S. Defense Threat Reduction Agency. ” < p > < p > Russian Foreign Ministry spokesman Zakharova previously said that “it cannot be ruled out that Americans use these laboratories in third countries to develop and modify pathogens of various dangerous diseases, including for military purposes.”. Russian Foreign Minister Sergei Lavrov also pointed out that the United States intensively deploys biological laboratories and is unwilling to disclose the research contents. Its behavior and purpose are questionable, and it is necessary to verify them. < / P > < p > in recent years, the United States has been expanding biological laboratories abroad, but there are some problems such as lack of supervision. The United States has also been exclusively opposed to the negotiation of the verification protocol of the Convention on the grounds that the biological field is not verifiable and that international verification “may threaten the national interests and commercial secrets of the United States”. < / P > < p > the website of the new Yorker magazine points out that the management of biosafety laboratories in the United States is still “unorganized”, and some irresponsible research has major security risks. Taking South Korea as an example, the Ministry of defense of South Korea reported that the US military laboratory in Wushan base is a class II biosafety laboratory. However, South Korean experts pointed out that the research on Bacillus anthracis should be carried out in a class III biosafety laboratory. There is a major hidden danger of virus leakage in the US military laboratory, and the US military Wushan base is in a busy market. Once the virus is leaked, the consequences are unimaginable. < / P > < p > a 2016 article by Philippa renzos, senior researcher of King’s College London, UK, and Gregory Koblenz, biosafety expert of George Mason University, USA, pointed out that the number of laboratories engaged in research on dangerous pathogens in the United States has increased rapidly in many parts of the world, including the increased risks of accidental leakage, human infection, theft, etc. < / P > < p > Li Zhangxi, a well-known expert in international law in South Korea and honorary professor of South Korea Foreign Studies University, wrote that as a state party to the Convention, the United States has violated the provisions of the treaty. He called on the US military to immediately stop “Jupiter” and other related plans and destroy all biological and chemical weapons at US bases in South Korea. < p > < p > Yu Shougen, director of the South Korean Institute for peace and people’s livelihood, told this newspaper that the US military’s research on biological and chemical weapons overseas completely ignores the security of other countries. The United States should take a responsible attitude to eliminate public doubts and effectively protect the life, health and safety of the Korean people. On July 10, Medvedev, vice president of the Russian Security Council, said that it is doubtful that the United States operates laboratories in a third country. Medvedev published an article in the Russian magazine in global politics, calling on the United States to abide by the Convention and increase transparency. Patrushev, Secretary of the Russian Security Council, pointed out that the United States needs to ensure that the research work of laboratories is as open and transparent as possible, so as to eliminate the speculation on biological laboratories from all walks of life.
