BlockBeats News, June 20th, according to The New York Times report, the recent preliminary agreement between the U.S. and Iran has encountered significant turmoil in the advancement process, with key details still unclear, including whether the Strait of Hormuz will maintain free passage and other core terms.

The report stated that the agreement has sparked disagreements less than a week after its release, including the cancellation of the planned signing or negotiation arrangement in Switzerland, the sudden cancellation of U.S. Vice President JD Vance's trip, and the indefinite postponement of further talks. The Swiss Foreign Ministry said that the relevant preparations are still ongoing, but the negotiations have been suspended with no resumption timetable.

The agreement itself also faces significant uncertainties. Both the U.S. and Iran have differing interpretations of the terms, with the U.S. claiming the agreement includes more commitments while Iran has not confirmed. Key issues, including the Iranian nuclear program arrangements, sanction relief mechanisms, and freedom of navigation in the Strait of Hormuz, have all been postponed for further discussion in a 60-day cycle, but subsequent talks are currently on hold.

Meanwhile, the U.S. and Israel hold distinctly different positions on the agreement, with Israel stating that it is not bound by the agreement and will continue military operations in the region, further intensifying the uncertainty of the situation.

Analysts point out that while this agreement is seen as an attempt to ease tensions in the Middle East, the lack of a clear implementation framework and ongoing negotiation mechanism poses a significant challenge to its stability, leading to increased uncertainty in the global energy and shipping markets.
