The Strait of Hormuz will remain closed until the United States accepts Tehran's seven-day plan to reopen the vital waterway, Iran's top negotiator and parliament speaker announced Sunday.

Mohammad Bagher Ghalibaf, speaking to Iranian state-linked news agency Nournews, stated that Washington had presented "some proposals through a mediator" following Iran's submission of a diplomatic roadmap. Ghalibaf emphasized that "the era of wasting time and dictating unilateral demands is over" and that Iran's position is "clear and definite."

Iran's conditions for reopening the strait are based on the "Islamabad memorandum," Ghalibaf added, asserting that Iran "will confront them with new surprises" on the military battlefield. He indicated that Iran would "both fight and negotiate," showing neither "excitement" nor being "intimidated" by the latest US proposals.

This development follows U.S. President Donald Trump's rejection of an Iranian proposal to reopen the Strait of Hormuz last week, just days after Iran put forward its roadmap. The strait is a critical chokepoint through which approximately one-fifth of the world's oil and natural gas is shipped during peacetime.

Iranian Foreign Minister Abbas Araghchi reiterated the nation's commitment to diplomatic solutions while also emphasizing self-defense capabilities. Speaking to foreign ambassadors and diplomats in Tehran, Araghchi stated that Iran had clearly outlined its conditions for reopening the strait and expressed hope that Washington would embrace diplomacy.

However, Araghchi issued a warning: if the U.S. initiates further military action, Iran is "more prepared than before and will take whatever action is necessary to defend ourselves." Ministry of Foreign Affairs spokesman Esmaeil Baghaei noted that Iran had used the UN General Assembly platform to communicate its stance on ending the "US-Israel war on Iran."

Baghaei highlighted that while the U.S. has maintained its focus on nuclear talks, Iran's primary objective has been the reopening of the Strait of Hormuz. "We are at this stage mainly focusing on the strait, and our principal concern is to reach a solution and to have peace and stability restored within this," he said.

Reopening the Strait of Hormuz has been Iran's main goal, according to the Ministry of Foreign Affairs, contrasting with the U.S. continued focus on nuclear negotiations. The situation underscores a significant divergence in priorities between the two nations regarding regional security and economic stability.
