United States President Donald Trump said “I will do what I have to do” if Iran does not stick to its agreement with Washington, Reuters reports.

“If Iran doesn’t live up to their agreement, or if they’re not behaving, I will do what I have to do,” Trump told reporters.

Trump also said Iran was supposed to use the money being unfrozen to buy food exclusively from the US, while Iran’s semi-official Tasnim news agency cited Iranian central bank governor Abdolnaser Hemmati saying that Tehran is under no obligation to purchase agricultural inputs from the US under the current memorandum of understanding.

“All that money’s coming back in the form of purchases of food which they desperately need. They have 91 million people, they can’t feed them. So, the money that we lift is going to go to our farmers,” Trump asserted.
