Vance has suggested that funds from unfrozen Iranian assets should be directed toward purchasing American agricultural products, specifically soybeans.
The proposal frames the potential release of capital as a mechanism to support Iran’s population while simultaneously boosting revenue for US farmers.
Vance described the arrangement as a "classic Trump deal," emphasizing the dual benefit of humanitarian aid and economic gain for American producers.
The comments were made on Monday, following recent diplomatic discussions in Switzerland.
The suggestion comes amid reports that President Donald Trump expects to sign a diplomatic agreement with Iran in the near term.
Earlier this week, the US government pledged that any unfreezing of Iranian assets would be structured to prevent the funds from financing terrorism.
