CHAKIB Khelil, president of the Organization of Petroleum Exporting Countries, said oil prices may continue to rise because of the weak US dollar and market speculation, Bloomberg News said.

"International markets need refined products not crude oil, of which there is enough in the market," Khelil said at a press conference in Algiers with visiting French Environment Minister Jean-Louis Borloo.

Crude oil futures in New York have risen 33 percent this year. Khelil said OPEC won't review the market situation until it meets in Vienna on September 9.

"OPEC doesn't have the control of the majority of production, we cannot do much for prices," Khelil said.
