MADRID, Spain (CNN) — Saudi Arabia on Tuesday ruled out further increases in crude production following its June 23 announcement that it would pump an extra half-million barrels a day.

In an interview with CNN, Saudi Oil Minister Ali al-Naimi said he was troubled by the current high levels of petroleum prices, but added, “We have nothing to do with prices where they are today.”

He denied the problem is one of immediate oil supply.

Asked whether Saudi Arabia, OPEC’s leading producer, would open its taps to its reported maximum capacity of 11 million barrels a day, al-Naimi did not dispute the figure but asked rhetorically, “Where is the buyer?”

Al-Naimi was speaking to CNN on the sidelines of the four-day World Petroleum Congress in Madrid, Spain, where leaders of the oil industry from around the world are meeting. They include government ministers, national oil company leaders, and international oil company bosses.

Al-Naimi ruled out an option advanced by some oil-watchers: to make more Saudi Arabia heavy crude available, but at a discount in order to bring prices down.
