US and Iran have different stances on the "threshold issue", and the progress of the agreement is set to determine the direction of the G7 summit.

Li Zixin, assistant researcher at the Chinese Academy of International Studies, stated: Regarding the upcoming G7 summit, on one hand, if the US and Iran can sign a memorandum during or before the summit, Trump will lead the entire agenda as a peacemaker, and the Middle East issue will shift from crisis management to the implementation of agreements. Additionally, the maritime escort alliance promoted by France and the UK may also enter a technical discussion stage, leading to a significant easing of the summit atmosphere. On the other hand, if the agreement signing is delayed, the issue of passage through the Strait of Hormuz will become the sharpest pain point of this summit, as well as a key issue of pressure on the US from all sides. This could lead to the G7 summit this year once again failing to issue a joint statement, and the transatlantic relationship may face deeper divisions. From this perspective, the White House will also work vigorously to facilitate the signing of a memorandum of understanding with Iran.
