LONDON, Jan 11 (Reuters) - Oil prices rose 1 percent on Monday, hitting a fresh 15-month high above $83 a barrel, supported by data showing China's crude oil imports surged by nearly 25 percent in December and as the U.S. dollar weakened.
The prolonged cold snap in the U.S. and Europe continued to boost demand for heating fuel, lending support to oil prices. [
]U.S. crude for February delivery <CLc1> rose 67 cents to $83.42 a barrel by 0958 GMT, off an earlier peak of $83.67, the highest price since October 2008.
London Brent crude <LCOc1> gained 60 cents to $81.97.
But oil is still 43 percent below its July 2008 high of more than $147 a barrel.
"The weak U.S. dollar, cold weather and robust Chinese import data are all supporting oil today," said Carsten Fritsch, oil analyst at Commerzbank in Frankfurt.
"At the moment the market is only looking at positive data, not negative numbers," he added.
China, the world's second-largest energy consumer, imported over 20 million tonnes of crude for the first time ever in December, up almost a quarter from November, according to Customs data published on Sunday. [
