The United States and Iran sought on Sunday to finalize an agreement to formally end the Middle East war after Donald Trump said a proposal that included opening the blockaded Strait of Hormuz was "largely negotiated".However, the US president emphasized that the deal was still "subject to finalization", while the New York Times reported that the two sides would only address thorny issues about Iran's nuclear program after an initial pact was reached."An Agreement has been largely negotiated, subject to finalization between the United States of America, the Islamic Republic of Iran, and the various other Countries," Trump wrote on his Truth Social platform on Saturday."In addition to many other elements of the Agreement, the Strait of Hormuz will be opened," he said, a development that would bring relief to global energy markets after a months-long Iranian blockade of the crucial thoroughfare for oil shipments.Leaders from Middle Eastern countries incuding Saudi Arabia, the United Arab Emirates, Qatar, Egypt, Jordan and Bahrain, as well as representatives from Turkey and Pakistan, joined a call with Trump to discuss the deal on Saturday, the US president said.Pakistan, which mediated historic face-to-face negotiations between US and Iranian delegations in April, hoped to host another round of talks "very soon," Prime Minister Shehbaz Sharif said.He said Pakistan's powerful army chief Asim Munir, who visited Tehran on Friday, also joined the call, which "provided a useful opportunity to exchange views on... how to move the ongoing peace efforts forward to bring lasting peace in the region."Trump said a separate call with Israeli Prime Minister Benjamin Netanyahu "went very well." US-Israeli strikes on Iran on February 28 sparked the war, with fighting persisting for weeks before a temporary ceasefire came into force in April.
