Stopping or delaying more than 4,000 trucks crossing the Iran-Turkey border and raising the cost of sea transportation have heightened concerns about moving goods and supplying people's basic needs. According to the head of the Transportation Committee of the Tehran Chamber of Commerce, the cost of transporting a 40-foot container from China has risen from $2,700 to $2,800 to $13,600. There have been reports of similar problems on Iraqi and Pakistani lines, increasing pressure on traders and transport companies. An interview with Narges was overheard, the Iran International Reporter.
