OREANDA-NEWS. June 15, 2011. PetroChina has completed all pipeline-laying work for the country's longest gas trunk and aims to start operating the pipe by the end of this month, the China Petroleum Daily reported on Tuesday.

The progress of the 142.2 billion yuan (USD 22 billion) project was largely in line with an earlier schedule.

The trunk line, or the second West-to-East pipeline, was designed to take 30 billion cubic metres of gas a year from Turkmenistan via the China-Central Asia gas pipeline. The line spans 4,865 km (3,020 miles) from northwestern Xinjiang to southern Guangzhou, capital of Guangdong province.
