Iran will not reopen the Strait of Hormuz until the US ends its naval blockade and meets Tehran's demands, foreign ministry spokesman Esmaeil Baghaei said on November 2.

Speaking at his weekly news conference in Tehran, Baghaei said Iran had passed all its demands to the US side through Qatari mediators and that "the ball is in America's court". A deputy foreign minister had travelled to Doha to facilitate the exchanges, which are continuing, he said.

The talks are based on Iran's seven-step plan, which has been compressed so it could be implemented within two days if Iran's demands are met, Baghaei said. Foreign Minister Abbas Araghchi set out the two-day timetable on November 1.

Baghaei said a recent letter from US Vice President JD Vance to Mohsen Rezaei, secretary of the Supreme National Security Council, did not launch any new initiative, and that Rezaei would decide how to reply.

Vance was chief negotiator of the Islamabad memorandum, which Baghaei said Washington breached within two to three weeks by letting tankers through the disputed Strait of Hormuz. Parliament speaker Mohammad Bagher Ghalibaf remains Iran's negotiator, he added.

Responding to Anwar Gargash, diplomatic adviser to the UAE president, who said trust between Abu Dhabi and Tehran had been shaken, Baghaei said Iran could not stay silent when the territory of regional states was used to attack it. Some countries had not only failed to stop the US using their facilities but had encouraged it, he said.

Baghaei rejected accusations of antisemitism as "a European phenomenon", saying Iran has about 100 synagogues, 13 or 14 of them in Yazd. Asked whether Iran's enriched uranium could be sent abroad, he said no, adding that Iran remains a party to the Nuclear Non-Proliferation Treaty.

Separately, Chinese foreign ministry spokeswoman Mao Ning said special envoy Zhai Jun would visit Iran, Oman and Saudi Arabia in early to mid-November. The announcement followed Oman's sultan's visit to Beijing, where sources said Muscat was reviving its mediation with Chinese backing.

The strait has been largely closed since late February, with daily transits down from about 140 to fewer than 10, according to sister agency Newsbase.
