China has urged the US to clarify its biological activities for military purposes both at home and abroad.

On Monday, the Russian defense ministry made public a presentation in which it stated that the US spent more than $200 million on the work of biological laboratories in Ukraine and that the laboratories of the Ukrainian Defense Ministry's central sanitary and epidemiological directorate participated in the US military biological program.

Igor Kirillov, the head of the radiation, chemical, and biological defense of the Russian armed forces, reported that Russian forces found 30 biological laboratories in Ukraine, possibly used to develop biological weapons.

Furthermore, Russian Defense Ministry Spokesperson Major General Igor Konashenkov revealed on Sunday that Kiev was urgently covering up traces of a military biological program carried out in Ukraine and funded by the Pentagon.

Since the beginning of Russia's operation in Ukraine, the Pentagon has been deeply concerned about the disclosure of its secret biological experiments in the country, he tersely added.

The top Russian figure went on to say that the Russian side has also received documents from workers at Ukrainian biological laboratories confirming the development of biological weapons in the country.
