Unfortunately, Arabs are brought to heel by Iran, and they might not be willing to ally with Pakistan against it again. In principle, continual Houthi strikes on KSA should give cause to the Saudis to team up with us again.
China has been unable to have Iran dislodge BLF involved in attacking its interests and citizens in Pakistan. I am at a loss that how could a 400 billion USD investment package for an international pariah like Iran not win the Chinese leverage over it still. Please do not be too hot on the idea of China practicing its leverage. Iran has taken a position contrary to the Chinese one already vis a vis Afghanistan. Chinese say Talis could do whatever they like in Afghanistan. They would not interfere because they see them as trustworthy interlocuters who would allow China to establish a foothold in Afghanistan and tap its rare earth mineral wealth. Iran is on a collision course with talis alternatively.
