An Iranian pavilion at the Riyadh Season festival in Saudi Arabia is drawing crowds with its display of saffron, one of the world's most expensive spices. The pavilion is offering visitors a chance to sample saffron in various forms and learn about its culinary uses. The Riyadh Season, which has attracted 6 million visitors in five weeks, is part of Saudi Arabia's efforts to diversify its economy and promote tourism. The festival includes 14 zones, 11 world championships, and 10 exhibitions. The presence of the Iranian pavilion marks a continuation of improving relations between Iran and Saudi Arabia, following the resumption of diplomatic ties last year.
