Saudi Arabia may further ease restrictions on foreign ownership in the economy and overhaul visa systems as the kingdom seeks to draw investors to help reduce its reliance on oil exports. The world's biggest oil exporter is considering allowing foreigners to own 100 percent of a company in at least four more industries, Mohanud Helal, secretary general of the Economic Cities Authority, said in an interview with Bloomberg. Retail and wholesale will be opened fully, from a 75 percent limit now, once rules are approved, Abdullatif Al-Othman, governor of the Saudi Arabian General Investment Authority, said on Monday. Foreign investments in non-oil industries are also crucial to create jobs for Saudi nationals in the private sector. Almost 90 percent of private-sector jobs created in five out of the six-nation Gulf Cooperation Countries between 2000 and 2010 went to expatriates, according to the International Monetary Fund. Nationals filled over 70 percent of public-sector jobs. "The decision had already been made on some of the industries," Helal said. The Saudi Arabian General Investment Authority (SAGIA) has identified about four sectors in which full foreign ownership may be permitted, he added without elaborating. Calls made to SAGIA after office hours weren't immediately returned. "SAGIA welcomes feedback from any investor on any regulation that will enable them to expand and grow theirinvestment in Saudi Arabia," said Al-Othman, the SAGIA governor. "We would love anyone to say look, if you change this law or regulation, I am coming here with these investments. Any regulation." Officials are also weighing plans to sell stakes in state-owned entities from hospitals to airports and even Saudi Arabian Oil Co., the kingdom's biggest oil company, known as Aramco. The country is also reviewing its visa system by looking for ways to accelerate the process of issuing work and visit permits, according to Helal, who heads the regulatory body governing four economic cities, including King Abdullah Economic City. "It is a very important and much needed step," said Mohammed Alsuwayed, the Riyadh-based head of capital and money markets at Adeem Capital. "We need foreign investors to contribute to the expansion of the Saudi economy, specifically the private sector and for them to better understand what or where they are putting their money in, they need to be allowed better access into the kingdom." Authorities are looking at allowing visitors, including pilgrims, to visit landmarks in various parts of the country through tourist visas. Enabling workers to bring family in easily is another area which is being considered, Helal said. — Agencies
