“The Iranian regime continues to use the proceeds from the nation’s vast oil resources to advance its narrow, alarming self-interests at the expense of the Iranian people,” said Secretary of the Treasury Scott Bessent said in a statement.
“Treasury will fight and disrupt any attempts by the regime to fund its destabilizing activities and further its dangerous agenda.”
US President Donald Trump reinstated his so-called maximum pressure campaign of sanctions on Iran last month in a bid to bring oil revenues upon which the state relies to zero and force Tehran to the negotiating table over its nuclear program.
The sanctions announced on Thursday also included entities in China and India the treasury accused of owning and operating vessels involved in the trade of Iranian oil - dubbed a "shadow fleet" by Washington.
Iran's oil ministry criticized the move and said it would circumvent US sanctions.
"The sanctions on Mohsen Paknejad are due to his extensive efforts to sell Iranian oil. He has repeatedly emphasized that Iranian oil exports will never stop and that the US policy of maximum pressure has failed," it said in a statement.
"In recent years, Iran has repeatedly demonstrated its ability to bypass sanctions and continues to sell its oil in international markets through various methods," it added.
