It is noted that these measures were applied due to the fact that Russia, according to the US, "did not provide guarantees under American law."
As specified, we are talking about the law "On the control of chemical and biological weapons," which was applied because of the incident in Salisbury.
Earlier, the publication Politico reported that the American leader Donald Trump signed a decree on the introduction of a second package of sanctions against Russia in connection with the case of Skripale.
The first package was introduced in August 2018 and provided for restrictions, mainly related to the sale of weapons and dual-use products.
