The Secretary of State has imposed sanctions on six entities and eight individuals for their involvement in significant transactions related to petroleum products from Iran. These sanctions aim to block their property, restrict financial dealings, and limit their ability to interact with U.S. financial systems. Additionally, the U.S. will deny visas or entry to those identified as corporate officers or principal owners of these sanctioned entities. This action is part of the U.S. government's efforts to enforce its foreign policy under Executive Order 13846.
Simple Explanation
The U.S. government is saying "no" to certain companies and people from Iran by stopping them from doing business with U.S. banks and visiting the U.S., because these people were involved with selling oil.
