The United States supports Gulf countries contributing hundreds of billions of dollars to Iran, but will not contribute itself, according to Vice President JD Vance.The subject of funds either given to or made available for Iran has been a primary source of questions as the Trump administration prepares to sign its Memorandum of Understanding with Tehran on Friday.“That’s the sort of thing they could have access to, funded by the Gulf Coast Coalition, so long as they honor their end of the obligation,” Vance told CBS News on Monday, when asked whether the U.S.-Iran memorandum electronically signed Sunday allowed for a “$300 billion reconstruction fund.”

He emphasized that the U.S. would not contribute to this effort, which would be used for reconstruction, and that Iran would have to meet certain criteria to get the funds.

“We absolutely are open to the Gulf Coast countries investing in the reconstruction of Iran, but only if Iran ends their nuclear program, ends their enriched stockpile of material, and is really open to an inspections and enforcement regime that gives the American people confidence they’re never going to have a nuclear weapon,” Vance said.

In a subsequent interview with Fox News’s Sean Hannity, he said, “Iranians don’t get a dime unless they behave and change their behavior,” and will “never get a dime of American taxpayer money. Ever. Full stop. Not even close.”
