Islamabad upgrades traffic control in preparation for US-Iran negotiations.

This morning, the ban on heavy vehicles entering the capital of Pakistan officially took effect, with enhanced control at local long-distance bus stations and shortened operations of the subway and public transportation. The core logic behind this traffic upgrade in Islamabad is to enhance a "mutual trust" atmosphere, using the absolute safety of physical space to make up for the weak foundation of diplomatic trust, proving to Washington and Tehran that Islamabad's negotiating table is not only a geographical transit point, but also an absolute security island in terms of information and security. The official schedule for the new round of negotiations between the United States and Iran has not been announced by Pakistani authorities.
