The world's largest oil exporter Saudi Arabia will do all it can to stabilise global oil markets, though geopolitics and speculation as well as fundamentals are behind high prices, the state news agency said.

'Saudi Arabia looks with great interest to oil price stability in the global market that will protect the interests of producers and consumers equally and world economic growth, especially in developing countries,' the Saudi Press Agency (SPA) said.

'Saudi Arabia, as the world's biggest oil exporter, has not and will not spare any effort to achieve this aim. Its oil policy aims always to foster and strengthen cooperation and dialogue between oil producing and consuming nations.'

It said that a meeting of crude producers and consumers called by Saudi Arabia tomorrow proved its commitment to market stability despite its conviction that oil prices are determined by 'various market supply and demand factors, commercial stock levels in consuming countries and the effect on the oil market of political instability and speculation.'

Consumers and producers blame each other for an oil price rally that has sparked protests from Brussels to Bangkok and threatens world economic growth.

Saudi Arabia summoned all sides and chief executives from big oil companies to meet in Jeddah after an unprecedented day of trading sent a shock through the oil market on June 6. Crude oil price has more than doubled in a year to nearly $140 a barrel, an almost sevenfold rise since 2002.

Saudi Arabia will lay on a tour of the expansion of the Khurais field on the second day of the conference, SPA said, reiterating that the plant would be ready by the middle of next year and bring an extra 1.2 million barrels per day online.

Saudi Arabia aims to boost output capacity to 12.5m bpd by the end of next year from around 11.3m bpd.
