Andrew England & Carola Hoyos Saudi Arabia says it will increase production by around 200,000 barrels per day in July. Saudi Arabia's decision to pump more oil than it has in nearly 30 years risks being completely negated by the sharp drop in output caused by attacks on production facilities in Nigeria. Nigeria now pumps less than 1.5 million barrels a day, rather than the 2.5 million b/d it has the ability to produce, the lowest level in 25 years, according to officials attending Sunday's high-level meeting in Jeddah. At the conference, attended by Gordon Brown, the British prime minister, as well as energy ministers and chief executives from around the world, Saudi Arabia confirmed it would pump 9.7 million barrels a day next month, an increase of 200,000 and the highest level in nearly 30 years, and repeated its standard offer of extra barrels if customers demanded them. The outcome of the hastily convened talks is likely to be seen as a disappointment because it yielded little more than had been expected from the world's largest exporter in spite of global concerns that developing countries were cracking under the burden of record oil and food prices. The kingdom reiterated its promise to expand production capacity, noting that it could add another 2.5m barrels of potential supply, to the 12.5 million b/d it expects to achieve after an exhaustive investment programme. Ali Naimi, Saudi Arabia's energy minister, said in a speech: "This will enable us to maintain our spare capacity in the interest of global market stability
