Dai Bing, China's deputy permanent representative to the United Nations (UN), on Wednesday called on the international community to assess documents on U.S. military biological activities, which were published by the Russian government, to alleviate the "great concern" of the international community. 

"China firmly opposes the development, stockpiling or use of biological and chemical weapons by any country under any circumstances and urges countries that have not done so to destroy their chemical weapons stockpiles as soon as possible," Dai said during the UN Security Council Arria Formula Meeting on biological security, hosted by Russia.
