The Biden administration has reportedly green lighted a sanctions waiver last week allowing Iraq to pay its electricity debts to Iran.

A non-public sanctions waiver issued by Secretary of State Antony Blinken and transmitted to Congress earlier this week authorizes Iraq to pay Iran for multimillion-dollar electricity debts, according to a copy of the notice, the Washington Free Beacon has claimed.

The waiver was issued a day after Biden administration officials denied Iran's claims that the United States had paved the way for Tehran to receive the $500 million, which was first reported by the Free Beacon.

The latest sanctions waiver, however, permits "the Trade Bank of Iraq to engage in financial transactions … with the Central Bank of Iran in connection with the purchase of electricity."

According to the report, it is unclear how Iran arrived at the $500 million figure, or if it is related to this most recent sanctions waiver, which does not detail specific amounts of money.

The report further claims that Iranian officials have said that they are owed around $18 billion from Iraq in back payments for electricity.
