Iran live updates: Trump says Iran will have to agree to 'Major Weapons Inspections'

Hours after Vice President JD Vance announced from Switzerland that Iran agreed to let international nuclear inspectors into the country, President Donald Trump said on social media that Iran will have to "agree to have Major Weapons Inspections" for a long period of time.

"Everybody is fully aware that Iran will agree to have Major Weapons Inspections in order to ensure 'Nuclear Honesty' long into the future," Trump said in the post.

Inspections were part of the Obama-era agreement that Trump canceled during his first term, after which Iran stopped letting international inspectors in.

The Trump administration has formally issued a waiver on the sale on Iranian oil, following through on a promise from the Memorandum of Understanding signed by President Donald Trump.

The waiver legalizes the sale of Iranian oil and allows transactions involving vessels that had been previously sanctioned.

The sanctions will be waived for a 60-day period beginning Monday and ending at 12:01 a.m. ET on Aug. 21.

The waiver also allows for "any payment of funds owed to Iran, the Government of Iran, or any blocked person for the purchase of crude oil" to be made in U.S. dollars.

The waiver does not, however, allow the sanctions on Iranian oil to be lifted for people in North Korea, Cuba and parts of Ukraine like Crimea.
