The sticking point in the US-Iran negotiations centers on the Strait of Hormuz, while other frameworks have been finalized.

According to a reporter from Italy's "La Repubblica," as of 01:57 Islamabad time on April 12, the US-Iran talks are ongoing, with both sides having been in the same room at the Serena Hotel for nearly 10 hours, with several breaks during that time.
The negotiations demonstrate strong determination, with frameworks for regional security, humanitarian reconstruction, and freezing funds already established.
The difficulty lies in the issue of the Strait of Hormuz, which could provide a key point of intervention for other regional and global participants.
