Negotiations between Washington and Tehran have reached a critical juncture as Iran officially confirms it is reviewing a new U.S. proposal delivered through Pakistani mediators. Iranian Foreign Ministry spokesman Esmaeil Baqaei stated that Tehran is examining the American points of view but reiterated demands for the release of frozen assets and an end to the U.S. blockade on Iranian ports. President Donald Trump characterized the talks as being in the 'final stages,' though he clarified that the administration is 'in no hurry' and will not provide sanctions relief before an agreement is finalized. On the military front, U.S. Central Command reported that American forces boarded the Iranian-flagged tanker M/T Celestial Sea in the Gulf of Oman on Wednesday. After a search for suspected blockade violations, the vessel was released and directed to alter its course. Simultaneously, Tehran has intensified its operational grip on the Strait of Hormuz, introducing new authorization requirements for vessels entering designated maritime zones while claiming to have coordinated the passage of 26 vessels in a 24-hour period. Diplomatic pressure is mounting from regional powers, with Turkish President Recep Tayyip Erdogan holding a phone call with President Trump to advocate for a 'reasonable solution.' Pakistan has also increased its mediation efforts, with Interior Minister Mohsin Naqvi reportedly visiting Tehran for the second time in a week to meet with IRGC leadership. Despite these diplomatic signs, the global energy market remains under severe strain, with hundreds of tankers still blocked from exiting the Gulf in what has been described as a historic disruption to global energy supplies.
