Plans are afoot for an American-owned company seized by the Kremlin and placed under state control to be used to supply food to the Russian army, a document seen by Reuters showed, potentially threatening Moscow’s warming relations with the U.S.

As the U.S. and the Kremlin negotiate to stop the war in Ukraine, the canned food maker Glavprodukt which was seized in October and is the only American-owned firm to be taken under state control, has been caught in the crosshairs.

The seizure was necessary to ensure stable production, including for future supplies to the national guard and defence ministry, according to a letter, reviewed by Reuters, addressed to Russia’s prosecutor general from Glavprodukt’s new management.

Glavprodukt is now under the control of Russia’s federal property management agency Rosimushchestvo having been seized from Los Angeles-based Leonid Smirnov.
