Washington — CNN revealed Sunday morning that a Qatari delegation, in coordination with the United States, arrived in Tehran to help complete the memorandum of understanding between the Americans and Iranians. Plans call for signing the document electronically to avoid last-minute disruptions.

President Donald Trump had promised that Vice President J.D. Vance would personally attend the signing ceremony in Europe. However, Trump is scheduled to travel to France tomorrow for the G7 summit. Since the president and vice president rarely travel abroad simultaneously, Vance’s trip could have posed logistical issues. According to CNN, the parties agreed to use electronic signatures.

Some mediators expressed concern that delays in signing could increase the risk of setbacks or withdrawal by one or both sides. Saudi channel Al Arabiya reported Sunday that the signing ceremony will be attended by Vice President Vance and Iranian Parliament Speaker Mohammad Bagher Ghalibaf. The report, not yet confirmed by other sources, added that mediators from Pakistan and Qatar would also be present. Al Arabiya further claimed that once signed, the agreement would reopen the Strait of Hormuz for free passage.

Despite Iranian opposition, President Trump announced Saturday night that the memorandum of understanding would be signed. The deal would open a 60-day window for negotiations on Iran’s nuclear program, alongside reopening the Strait of Hormuz and lifting the U.S. blockade on Iranian ports.
