MOSCOW, May 24 (AFP) - Russia will cut oil export quotas by 1.2 million tonnes in the second quarter of the year as part of international efforts to bolster world oil prices, the fuel and energy ministry said Monday, Interfax news agency reported. Viktor Kalyuzhny, first deputy fuel and energy minister in the outgoing government who also heads the body which regulates access to export pipelines, signed the export cuts order on Friday, the agency said. Russia's integrated oil firms will be hardest hit by the reductions, according to ministry figures. The country's biggest oil producer LUKoil will see exports trimmed by 232,000 tonnes, Yukos 170,000, Surgutneftegaz 134,000, Tyumen Oil 80,000, Rosneft 70,000, Sibneft 61,000 and Sidanko 34,000. Russia exported 29.9 million tonnes of oil in the last quarter of 1998, and pledged to cut exports by 100,000 tonnes a day from April to no more than 28.7 million tonnes in the second quarter of 1999. Nevertheless, 1.2 million tonnes of export quotas from the first three months of the year have been carried over, as poor weather in Russian sea ports restricted overseas shipments. In March, oil exporting countries agreed to try and cut output by more than two million barrels a day, including 400,000 b/d from non-members of the Organisation of Petroleum Exporting Countries (OPEC). The cuts have seen world oil prices recover with Brent crude for June delivery trading in London last week at a shade under 15 dollars a barrel, compared to below 11 dollars in early March.
