KASHAN, Iran (AP) — The historic Kashan bazaar in central Iran once sat on a major caravan route, its silk carpets known the world over. But for the weavers trying to sell their rugs under its ancient arches, their world has only unraveled since the collapse of Iran’s nuclear deal with world powers and wider tensions with the West.

Rug exports, which exceeded $2 billion two decades ago, have plummeted to less than $50 million in the last year in the Persian calendar that ended in March, according to government customs figures. With fewer tourists coming and difficulties rising in making international transactions, Iranian rugs are going unsold as some weavers work for as little as $4 a day.

“Americans were some of our best customers,” said Ali Faez, the owner of one dusty carpet shop at the bazaar. “Rugs are a luxury product and they were eager to buy it and they used to make very good purchases. Unfortunately this has been cut — and the connection between the two countries for visitors to come and go has gone away.”
