The Second West-East Gas Pipeline, designed to deliver 30 billion cubic meters of gas per annum, will travel 8,653 kilometers through 15 provinces and regions from Xinjiang's Horgos in the west to Shanghai in the east, and to the south reaches at Guangzhou and Hong Kong. It is the first large scale pipeline project built to introduce overseas gas resources. The Pipeline is divided into an eastern segment and a western segment at Zhongwei County of Ningxia Hui Autonomous Region. The western segment consists of Horgos-Zhongwei Trunk Line and Zhongwei-Jingbian Cross-link Line. The eastern segment consists of Zhongwei-Guangzhou Line.

Part of the western segment, Zhongwei-Jingbian Cross-link Line separately connects the western segment to the First West-East Gas Pipeline and the Second Shaan-Jing Gas Pipeline. As an important hub of gas pipelines in China, Jingbian station boosts and dispatches imported Central Asian gas to Eastern China through the First West-East Gas Pipeline, and to Beijing and surrounding regions through the Shaan-Jing Gas Pipelines. The Second West-East Gas Pipeline, when completed, will be connected to more than ten established pipelines in China, and will be a backbone of guarantee in China's oil and gas pipeline system.

The blueprint of Central Asia-China Gas Pipeline, China's first pipeline to import overseas gas, was rolled out by an agreement of natural gas cooperation signed by Chinese President Hu Jintao and Turkmen President Saparmurat Niyazov in April, 2006. On December 14, 2009, the flow of natural gas through this pipeline was jointly turned on by Chinese, Turkmen, Kazakh, and Uzbek presidents.

On December 31, 2009, as a cross-link line of the pipeline network in northern Xinjiang been put into operation. Urumqi, the capital city of Xinjiang Uygur Autonomous Region, became the first consumer who was benefited by the natural gas from Central Asia..

Currently, gas production on the right bank of Amu Darya in Turkmenistan is well under way. The daily input volume at the initial station at Horgos is about 6.6 million cubic meters. Meanwhile, construction of the eastern segment of the pipeline is putting forward smoothly, with 1,560 kilometers already welded. The entire pipeline is expected to be completed and available for gas delivery by the end of 2011.

To the west, the Second West-East Gas Pipeline is connected to the 1,833km-long Central Asia-China Gas Pipeline, which starts at the border of Turkmenistan and Uzbekistan and runs through central Uzbekistan and southern Kazakhstan before entering China at Horgos.

By February 1, the Central Asia-China Gas Pipeline had introduced more than 400 million cubic meters of gas, including 264 million cubic meters already inputted to the initial station at Horgos. On an average day, the Second West-East Gas Pipeline supplies 1.5 million cubic meters of natural gas to Urumqi, and 5-6 million cubic meters to Beijing. It is expected that Turkmenistan will supply 5.8 billion cubic meters of gas to China in 2010.

The First West-East Gas Pipeline, 3,843 kilometers in length, runs from Tarim in Xinjiang in the west to Shanghai in the east with its gas supply covering Central and Eastern China. It became operational on October 1, 2004, capable of transporting 12 billion cubic meters annually.

The Second Shaan-Jing Gas Pipeline became operational in July 2005. It runs from Jingbian County in Shaanxi Province in the west to Beijing in the east via Shaanxi, Shanxi and Hebei provinces, with a total length of 935.4 kilometers and an annual deliverability of 12 billion cubic meters.
