According to the commander of Russia's Nuclear, Biological and Chemical Defense Forces, Lieutenant General Igor Kirillov, Moscow has obtained documents that suggest Kiev has continued to coordinate with the Pentagon in the military biological field, including the transfer of pathogenic biomaterials.

Kirillov pointed to an official appeal from 'ch2m-hill' – a key Pentagon contractor – to Ukrainian companies participating in a "program to counter particularly dangerous pathogens in Ukraine."

The document reports on the continuation of the Defense Threat Reduction Agency's (DTRA) biological program in Ukraine and outlines future tasks, such as consolidating collections of dangerous pathogens and deploying systems for managing bio risks and monitoring the epidemiological situation.

Kirillov also stated that, in January 2023, the government of Ukraine published a new set of requirements for the "accounting, storage, transportation and destruction" of various pathogens, which included instructions for the international transportation by air of substances with the highest hazard class. He noted that the transport document templates provided in the guidelines only featured examples of US labs as recipients or senders of the hazardous biomaterials.
