"According to the 1991 CBW Act, the American law about control of chemical and biological weapons, Russia could face guaranteed second round of sanctions because of the poisoning of Alexei Navalny; it is only possible to avoid it if Russia takes commitment to never deploy chemical weapons again", the Department of the State said.
The U.S. diplomatic office recommended that Russia declares and destroys its secret program of chemical weaponry stocks under international supervision.
In 2017, Russia claimed to have eliminated its stocks of chemical weapons. However, Washington blames Moscow for development of a secret program and storage of stocks of poisonous agents.
Earlier, the U.S. imposed sanctions against seven Russian officials within the Navalny case. Besides, the Department of the State added six companies to the list of sanctioned entities in the same case.
