CHINA'S crude oil imports rose for a 13th month in November as refiners in the fastest-growing major economy expanded production in a bid to end the worst fuel shortage in two years. Imports gained 0.5 percent from a year earlier to 13.61 million tons, about 3.3 million barrels a day, the General Administration of Customs said in Beijing yesterday. Purchases in the first 11 months jumped 12.5 percent to 150.3 million tons. Exports dropped 41 percent to 3.19 million tons in January to November and were 280,000 tons last month.
