**[Islamabad Traffic Control Upgraded in Preparation for U.S.-Iran Negotiations]** BlockBeats News, April 18 — In the early hours of April 18, a ban on heavy vehicles entering the city officially took effect in Pakistan's capital. Local long-distance bus stations have implemented stricter controls, and metro and bus operations have been shortened. The core logic behind Islamabad's traffic upgrade lies in fostering an atmosphere of "mutual trust." By ensuring absolute physical security, it aims to compensate for the weak foundation of diplomatic trust and demonstrate to Washington and Tehran that the negotiation table in Islamabad is not only a geographical transit point but also an absolute safe haven for information and security. As of now, the Pakistani government has not announced the timetable for the new round of U.S.-Iran negotiations. (Jin10)
