The current volume of trade between the Kingdom and Iran is about U.S. $500 million, but could be enhanced by cooperation in the production sectors of iron and steel works, car manufacturing, petrochemicals, and pharmaceuticals, as well as in the service fields of tourism, air and land transport, and the establishment of a joint marine company. Iranian commerce minister Muhammad Shariat-Madari, calling on the Saudi and Iranian private sector to contribute to enhancing bilateral economic relations, pointed out that Iran extends all possible facilities and incentives to foreign investors.
