Iran's foreign ministry on Monday said it was considering a two-day plan to reopen the Strait of Hormuz if the U.S. agrees to its conditions, having previously proposed a one-week timeline.

"The possibility of implementing this plan in two days is another indication of Iran's good-faith approach. We have stated that, if Iran's demands are met, it would be possible to restore security to the Strait of Hormuz and resume the negotiating process within a short period," said foreign ministry spokesman Esmaeil Baqaei, adding that the "exchange of messages is still ongoing" via mediators.

The United Arab Emirates' presidential adviser said Sunday that his country hopes a diplomatic breakthrough in Qatar-led mediations is possible to avert a new round of confrontation between the U.S. and Iran.

The Iran war, which began on Feb. 28 with joint strikes by the U.S. and Israel followed by attacks by Iran on the Gulf nations, has made it "a watershed year" for the region and the world, UAE presidential adviser Anwar Gargash said at a security forum in Bahrain.

Iran’s top diplomat said consultations with mediators are ongoing as diplomatic efforts try to avoid a return to all-out war, and the final outcome depends on answers provided by the United States to the “Iranian questions.”

In an interview shared on his Telegram channel, Abbas Araghchi said Iran hoped the U.S. would choose “diplomacy over other paths.” He said Iran was ready for both defense and diplomacy, depending on Washington’s “rationality."

The UAE is hoping for a breakthrough in negotiations between Iran and the United States while being prepared for the worst, a senior official said on Sunday, following threats of a resumption of the Middle East war.

Iran warned on Sunday that any new war with the United States could last longer than the previous conflict and that U.S. President Donald Trump would not be the one to determine its duration.

U.S. President Donald Trump said overnight that the United States has knocked out much of Iran's military but still has to "take care of" one or two targets, as Tehran warned of reprisals if attacked.

Trump maintained that negotiations with Iran to end the war, which was started by the United States and Israel in February, were "going fine but you know they're not very reliable."

Iran is studying the U.S. proposals contained in a letter from U.S. Vice President JD Vance, amid a positive atmosphere surrounding the path of negotiations and expectations of a breakthrough in the coming period, sources told Al-Arabiya television on Saturday.

Qatari mediators held talks in Tehran for more than 12 hours on Friday in an effort to reach a deal to restart direct negotiations between the U.S. and Iran and avoid an outbreak of war after the midterms, diplomatic sources told U.S. news portal Axios.

Iran's army warned Saturday that any new U.S. attack would only spread their war wider, following threats by America and Israel of further military action as they hold crucial elections.

Oman said on Friday it had rescued 25 sailors from a merchant ship that was targeted and set ablaze, as Iran reported three oil tankers were halted while crossing the blockaded Strait of Hormuz.
