BlockBeats News, May 18th, according to multiple media reports, regarding the latest negotiation progress between the United States and Iran, the two sides still have significant differences on core issues such as the nuclear issue, conditions for ending the war, and unfreezing frozen assets, but there have been limited adjustments on some technical arrangements.

Sources said that the U.S. side, in the latest proposal, allows Iran to conduct limited peaceful nuclear activities under the supervision of the International Atomic Energy Agency and is considering phased unfreezing of about a quarter of the frozen assets; the Iranian side insists on a full sanction removal and the return of related assets while opposing linking the nuclear issue to ceasefire conditions.

In terms of the negotiation framework, Iran has proposed accepting a long-term freeze of the nuclear program but refuses complete dismantlement, and suggests transferring some enriched uranium to a third country such as Russia, while also promoting the gradual resumption of navigation in the Strait of Hormuz and introducing a regional third-party coordination mechanism. Iran also advocates for economic facilitation measures to replace war reparations arrangements.

According to reports, the U.S. negotiation window is narrowing, with sources stating that Iran may have only "a few days instead of a few weeks" to submit a viable proposal; otherwise, the possibility of turning to a military option is not ruled out, indicating that the bargaining between the two sides has entered a key stage.
