ASHGABAT: Energy-rich Turkmenistan’s leader has ordered the start of construction on a pipeline carrying gas from the former Soviet state to India, Pakistan and Afghanistan, the government said on Saturday. President Gurbanguly Berdymukhamedov ordered state companies Turkmengaz and Turkmengazneftstroi to begin building the isolated republic’s section of the pipeline, state media said. Overall, the pipeline will stretch 1,800 kilometres (1,100 miles) and is likely to cost more than $10 billion (9.3 billion euros). The Turkmenistan official newspaper also said the government expects the gas link, with an annual capacity of 33 billion cubic metres, to be fully operational by the end of 2018. The Turkmenistan-Afghanistan-Pakistan-India (TAPI) project could help ease growing energy deficits in Asian giants India and Pakistan. For Turkmenistan, which has been hit by low energy prices and is dependent on China for the vast majority of its gas sales, TAPI is a key opportunity to diversify its exports.
