The Trump administration announced sanctions on eight companies involved in the sale of Iranian petrochemicals and said previous seizures of Iranian petroleum bound for Venezuela brought the US US$40 million (SS54.67 million) that will be given to American victims of terrorism.
The actions announced on Thursday (Oct 29) gave the administration a chance to highlight President Donald Trump's "maximum pressure" campaign against Iran less than a week before the Nov 3 election. His supporters have touted Mr Trump's tough action on Iran as a promise kept after he vowed in 2016 to restore sanctions and quit the Obama-era deal constraining the country's nuclear program.
As part of the coordinated actions on Thursday, the Treasury Department announced new sanctions against petrochemical firms and trading companies in Iran, Singapore and Hong Kong.
The department said those trades were worth tens of millions of dollars and went through a broker named Triliance Petrochemical Company Ltd., which was sanctioned in January.
Petrochemical sales are a key source of revenue for Iran, and the US alleges that the government uses it to finance a "destabilising agenda" in the Middle East and Venezuela, Treasury said in a statement.
"The United States remains devoted to targeting any revenue source the Iranian regime uses to fund terrorist groups and oppress the Iranian people," Treasury Secretary Steven Mnuchin said in the statement.
The agency says that Triliance uses front companies to continue selling and purchasing products from Iran.
At the same time, the Justice Department unsealed two earlier complaints: One detailing how the US had seized two shipments of antitank missiles and other weapons from Iran's Islamic Revolutionary Guard Corps that it says were intended for Yemen's Houthi rebels; and the other highlighting the US seizure of the petroleum that was bound for Venezuela.
"The two forfeiture complaints allege sophisticated schemes by the IRGC to secretly ship weapons to Yemen and fuel to Venezuela, countries that pose grave threats to the security and stability of their regions," John Demers, head of the department's national security division, told newsmen on a conference call.
The Justice Department said the US had sold off the petroleum and the US$40 million would go to the US Victims of State Sponsored Terrorism Fund.
The officials denied any political motivation for Thursday's announcements. But Elliott Abrams, the State Department's special representative on Iran and Venezuela, said the sanctions actionswhich brought this week's total of oil and petrochemical actions to 41had given the US leverage to bring Iran back to the table for a better deal than the one President Barack Obama's administration signed. He implied Democrat Joe Biden might squander it if he wins the presidency.
"We're building up tons of leverage and our hope is it will be used and used wisely and not simply discarded," Mr Abrams said. "That would be foolish and tragic."
