Saudi Arabia plans to increase its oil production by 200,000 barrels a day next month, the kingdom's oil minister told UN chief Ban Ki-moon on Sunday, according to Ban's spokesman. The UN secretary-general met with Oil Minister Ali al-Naimi in the port city of Jiddah during a one-day trip to the world's largest oil producer. Farhan Haq, a spokesman who is traveling with Ban, said in an e-mail that the UN chief said Naimi told him Saudi Arabia would increase oil production by 200,000 barrels a day from June to July. In May, the kingdom increased its production by 300,000. By July, production should be at 9.7 million barrels a day, Haq said.
