China's first transnational crude oil pipeline, the China-Kazakhstan Pipeline, allowed China to import 10.93 million tonnes of crude oil last year, authorities in west China's Xinjiang Uygur Autonomous Region said Thursday.

Statistics from the local government of the Bortala Mongol autonomous prefecture showed that last year's oil imports brought in through the pipeline hit a record high, growing by 10.3 percent from the previous year.

The 1,200-km-long pipeline, starting in the city of Atasu in Kazakhstan and ending at Petrochina Dushanzi Petrochemical Company after entering China at Alataw Pass in Xinjiang, went into formal operation in July 2006.

The amount of oil brought in by the pipeline has grown by 20 percent annually on average, with total oil imports exceeding 40 million tonnes as of December 2011.
