Oil-rich Kuwait is drawing up plans to ensure it meets its oil exports if neighbouring Iran closes a sea route that is critical to Gulf oil producers, a senior Kuwaiti official said on Monday. Saad al-Shuwaib, chief executive of Kuwait Petroleum Corporation, the state oil company, told the Kuwait news agency that “precautionary plans” to export Kuwaiti crude if the Strait of Hormuz was closed were in place, but not yet finalised. On Saturday, the head of Iran’s Revolutionary Guard was quoted as saying that if Iran was attacked it would impose controls on the Strait of Hormuz, a strategic waterway that connects the Gulf with the Indian Ocean and through which more than a third of the world’s exported oil passes.
