The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) has released a notice listing individuals, companies, and vessels that have been added to the OFAC's Specially Designated Nationals and Blocked Persons List (SDN List). This designation is based on various legal criteria, primarily relating to activities in the Russian Federation's energy and financial services sectors. The properties and interests of these entities, under the U.S. jurisdiction, are blocked, and American citizens and companies are generally restricted from conducting transactions with them. The notice includes detailed information, including dates, contact details, and online resources for further information on these sanctions.
Simple Explanation
The U.S. government has made a list of people and boats they don't want Americans to do business with because they are breaking important rules. If someone is on this list, it means their stuff in the U.S. is kind of "frozen," and people here should stay away from them.
