The Saudi pavilion at the 12th commercial exhibition of the member countries of the Organization of Islamic Countries, which concluded in Cairo today, ranked first, according to organizers. The 35-exhibitor Saudi pavilion attracted the largest turnout, who were impressed by the Saudi petrochemical, electric, plastic, mineral and foodstuffs products and building materials. The Saudi pavilion also occupied the first place in the previous exhibition held in Senegal. The 13th fair will be hosted by the United Arab Emirates city of Al-Sharqa in 2011.
