Rizai will meet Vance in Qatar next week as sources outline the US offer to Iran.
Sources say a Qatari-Pakistani proposal revives serious negotiations between Washington and Tehran. Under the proposed framework, the Strait of Hormuz will be opened and the naval blockade lifted immediately, and the US will release Iranian assets worth between 6 and 9 billion dollars if an agreement is reached. An initial agreement on the reduction of uranium enrichment was considered probable, when Washington allowed enrichment within Iran to 3.67% and Tehran agreed.
