The construction of an 4.000 km long pipeline for the transportation of natural gas from western China (Tarim oil field in Xinjiang) eastwards (Shanghai) is one of China's ten most important technological advancements in 2004.
The Xinjiang Autonomous Region is China's largest natural gas reserve with 229 billion m3. The pipeline connects this western region with coastal cities where the demand for energy is very high. More than a real technological advance, the construction of the pipeline is part of the campaign for the development of the regions of western China led by the government.
