Pipelines
As of 2006, China had 22,664 km (14,083 mi) of gas pipelines, 15,256 km (9,480 mi) of oil pipelines, and 6,106 km (3,794 mi) for refined products. Due to the growing dependence on oil and gas, the total length of oil and gas pipelines in China has risen to 70 000 km (0 mi) from 22 000 km (0 mi) in 1997, stretching from oil and gas fields in western and northeastern regions to densely populated coastal areas in the east. By the end of 2010, the network could exceed 90 000 km (0 mi).
China's pipelines carried 219.9 million tons of petroleum and natural gas in 2003. As a major oil and gas consumer, China is searching for more external supples. Construction of a 4,200-km-long pipeline from Xinjiang to Shanghai (West–East Gas Pipeline) was completed in 2004. The government hopes that the use of natural gas will assist to reduce the use of coal which is responsible for much air pollution.
