The sanctions will be in effect for two years.
The United States has imposed sanctions against three companies from Russia as part of a ban on the transfer of weapons of mass destruction technologies and their means of delivery to Iran, North Korea, and Syria.
The corresponding document of the State Department is posted on the website of the US Federal Register.
The research and production enterprise Pulsar, Charter Green Light Moscow and Asia-Invest LLC, and any of their subsidiaries were subject to restrictions.
The decision came into force on July 29.
The sanctions prohibit the conclusion of contracts with the persons involved in the list to purchase any goods and technologies, assistance to them from state structures, the sale of weapons to them, and the issuance of licenses for the purchase of goods that are subject to export control.
