On the afternoon of October 28, the Ministry of national defense held a regular press conference. Senior Colonel Tan Kefei, deputy director of the information bureau of the Ministry of national defense and spokesman of the Ministry of national defense, answered reporters' questions. Reporter: Recently, the foreign ministers of China and Russia issued a joint statement on strengthening the biological weapons convention, saying that the biological militarization activities carried out by the United States at home and abroad lack transparency, which has aroused the concern and doubt of the international community. What is your comment on this? Tan Kefei: Recently, the foreign ministers of China and Russia issued a joint statement on strengthening the biological weapons convention. The statement pointed out that the biological militarization activities carried out by the United States and its allies at home and abroad have aroused serious concerns and doubts about its compliance by the international community, posed serious risks to the national security of China and Russia, and damaged the security of relevant regions. As we all know, as the only country blocking the negotiation of the verification protocol of the biological weapons convention, the biological militarization activities of the United States have always attracted the attention of the international community. Even the United States' own media called the fort Detrick biological base "the center of the darkest experiment conducted by the U.S. government". People of insight in the United States and the international community have long been worried about the illegality, opacity and insecurity of the US activities in the base. The more than 200 biological laboratories currently deployed abroad by the United States have aroused widespread doubts and protests due to the lack of transparency in their activities. In addition, over the past 20 years, the United States has always refused to restart the negotiation of the Convention's verification protocol, opposed the establishment of the Convention's verification mechanism, and stubbornly stood on the opposite side of the international community, which has aroused greater doubts and concerns of all parties. Biological militarization is a major issue related to international peace and security and the security interests of all countries. We urge the United States to seriously respond to the concerns of the international community in an open, transparent and responsible manner, earnestly implement the obligations of States parties to the Convention and make a comprehensive explanation of its biological militarization activities at home and abroad.
