Workers in Daqing, northeast China's Heilongjiang Province, fill a bottle with part of the first flow of crude oil transported through the China-Russia oil pipeline on December 20, marking the nearly 1,000-km pipeline's readiness for full operation.

The website of the State-owned Assets Supervision and Administration Commission said about 300,000 tons of oil were pumped into the pipeline from Russia on December 12 and arrived at Daqing terminal on December 19.

The pipeline, operated by the China National Petroleum Corporation, is set to transport 15 million tons of crude oil from Russia to China annually for 20 years starting in 2011.

China and Russia signed an official agreement for the construction of the conduit in February 2009 and the construction on the 927-km section in China began in May 2009. Under the bilateral agreement, China will offer a total of $25 billion in loans to two Russian oil companies in exchange for 300 million tons of oil imports over 20 years.
