China’s state-owned PipeChina has started building the Chinese section of the Central Asia-China pipeline’s Line D, which will carry gas from Turkmenistan, Uzbekistan, Tajikistan and Kyrgyzstan to eastern China.

Also known as West-East Gas Pipeline 4, the line will span more than 4000 kilometres from Turkmenistan’s Galkynysh field to Shanghai and will have an initial throughput capacity of 15 billion cubic metres per annum, which could be doubled to 30 Bcm per annum.

PipeChina this week began construction of the 3340-kilometre section of the pipeline that starts at the Chinese side of the border with Kyrgyzstan at Wuqia County, on the western rim of the gas-rich Tarim basin.
