Beijing on October 21 raised serious concerns over the research activities of the United States in biological laboratories of relevant countries. Foreign Ministry spokesman Zhao Lijian said on the 21st that the relevant activities of the United States are not transparent, unsafe and unreasonable. The United States should face up to the concerns of the international community, earnestly fulfill its obligations under the Convention on the prohibition of biological weapons, and make a comprehensive clarification on the biological militarization activities outside the United States 。 At the regular meeting on the same day, there was a question: it was reported that Medvedev, vice chairman of the Russian Federation Security Council, said on the 20th that the research activities of the United States in the biological laboratories of CIS countries had aroused serious concern. Efforts are being made not only to expand these biological laboratories, but also to promote them in countries around the world. However, its research is opaque, which runs counter to the norms of the international community and international organizations. What is China’s comment on this? Zhao Lijian said that this is not the first time that the international community has expressed concern about the US bio militarization activities in other countries. China has repeatedly stressed that the relevant activities of the United States are opaque, unsafe and unreasonable. It is reported that the United States has many biological laboratories in 25 countries and regions, including the Middle East, Africa, Southeast Asia and the former Soviet Union, he said. The United States has set up 16 biological laboratories in Ukraine alone, some of which have experienced large-scale outbreaks of infectious diseases. According to USA today, hundreds of accidental human contact with lethal microorganisms have occurred in biological laboratories at home and abroad since 2003. These contacts may lead to direct contacts being infected by lethal viruses. The virus will spread to the community through these individuals, which will lead to epidemic situation. < / P > < p > “why does the United States build so many biological laboratories all over the world? Why should we build laboratories with the military as the leading force? What is their purpose? How much sensitive biological resources and information has the United States seized from relevant countries? Does the laboratory meet safety standards? Is there a potential leak? Why has the United States opposed the verification protocol of the biological weapons convention (BWC) exclusively for more than ten years? Only the US government can answer these questions, and only the US government can provide the truth. ” Zhao Lijian said. Zhao Lijian said that the United States should face up to the concerns of the international community in an open, transparent and responsible manner, earnestly fulfill its obligations under the Convention on the prohibition of biological weapons, make a comprehensive clarification on the US overseas bio militarization activities, and stop negotiations on the exclusive blocking verification protocol.
