The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) has added several individuals and vessels to its Specially Designated Nationals and Blocked Persons List (SDN List). This means the property and financial interests of these individuals, under U.S. jurisdiction, are blocked, and U.S. persons cannot conduct transactions with them. The listed vessels are linked to companies whose assets are blocked due to various executive orders. OFAC also updated information for a vessel already on the SDN List.
Simple Explanation
The U.S. government is telling people that they have a list of certain people and boats that Americans can’t do business with because those people did something wrong according to certain rules.
