Iranian Parliament Speaker Mohammad Baqer Qalibaf said on Tuesday Iran will not enter negotiations with the United States on a final agreement unless certain paragraphs of a recently signed peace memorandum of understanding (MoU) between the two sides are implemented.

Qalibaf, also the head of Iran's negotiating team, made the remarks in an interview with state-run IRIB TV while elaborating on the latest developments pertaining to the implementation of the peace MoU and talks with the United States.

He said Iran's recent trip to Switzerland sought to implement the MoU provisions for ending the war on all fronts, including Lebanon, lifting the US naval blockade, reopening the Strait of Hormuz, issuing US waivers for Iranian crude oil exports, and releasing frozen Iranian assets.

Unless these five preliminary paragraphs are fulfilled, the other paragraphs' implementation will not begin, Qalibaf said.

He said Iran, the United States and Lebanon agreed to form a joint committee to enforce the ceasefire, ensure the war's end in Lebanon, and uphold Lebanese sovereignty, adding that Iran and the United States, two of the three parties, had already named their representatives.

Iran both pursues the path of dialogue and responds with force wherever necessary, he added.

Meanwhile, Qatari Prime Minister and Foreign Minister Sheikh Mohammed bin Abdulrahman bin Jassim Al-Thani discussed regional developments and a ceasefire in Lebanon with US special envoy Steve Witkoff and Jared Kushner, Qatar's foreign ministry said on Tuesday.

On June 18, Iran and the United States signed the MoU on ending the war in the region. On June 22, technical negotiations between Iran and the United States began in Switzerland following high-level consultations between Iranian and US delegations the previous day with the mediation of Pakistan and Qatar.
