Saudi Arabia reclaimed its position from Russia as the largest crude supplier to China as OPEC members extended their global fight for market share. The world’s biggest oil exporter sold 3.99 million metric tons to China in October, 0.8 percent more than in September, data from the Beijing-based General Administration of Customs showed on Monday. Angola, another member of the Organization of Petroleum Exporting Countries, also surpassed Russia in shipping crude to the Asian nation.
