RIYADH, Jan 24 (Reuters) - This year could mark a turning point for oil demand as use in emerging countries catches up with the developed world, top exporter Saudi Arabia said on Monday, while voicing concern speculation could push prices higher.

"Global oil demand is expected to rise between 1.5 million to 1.8 million barrels per day this year," Ali al-Naimi told an industry conference in Riyadh.

The figure is higher than the forecast of the International Energy Agency, which represents consumers. [IEA/M]
