China, the world's top crude oil importer, took in 11.8 million barrels per day (bpd) of oil in September, up 5.5% from August and up 17.5% from a year earlier, customs data showed.

"The era of global oil demand growth will come to an end within the next 10 years, but in the absence in a large shift in government policies, I don't see a clear sign of a peak," IEA chief Fatih Birol told Reuters.
