US Vice President Vance stated on the 14th (local time) that he is "optimistic" about the current progress regarding the Iran issue. However, he added that significant distrust exists between the US and Iran, which cannot be resolved overnight. According to sources, Vice President Vance is expected to lead the second US-Iran negotiations if they take place, with President Trump's special envoy Witkoff and son-in-law Kushner also expected to participate. President Trump has entrusted these three individuals with pursuing diplomatic solutions and is continuously in contact with Iran and mediating countries. Currently, the US side is internally discussing the schedule for a second meeting, but whether it will be held and the specific timing have not yet been confirmed.
