As Washington and Tehran negotiate the implementation of an interim peace deal that ended the Iran war, the US has lifted restrictions on Iranian oil trade until August 21.

The sanctions relief is a central pillar of the peace framework that the two sides signed last week.

At the same time, the US and Qatar are looking into the release of around $6 billion (around €5.3 billion) from frozen Iranian oil revenues. According to US President Donald Trump, the money will be "used for the purchase of food and medical supplies, exclusively from the United States, including Corn, Wheat, and Soybeans from our great American farmers. These are things that are desperately needed by Iran."

Tehran denies any obligation to buy food from American farmers.

But it is clear that Iran badly needs the money — according to preliminary estimates by the Iranian government, the war with the US and Israel caused around €229 billion in damages.
