Within the space of three weeks, Turkmenistan has committed its entire gas exports to China, Russia and Iran. It has no urgent need of the pipelines that the United States and the European Union have been advancing. Are we hearing the faint notes of a Russia-China-Iran symphony?

The 182-kilometer Turkmen-Iranian pipeline starts modestly with the pumping of 8 billion cubic meters (bcm) of Turkmen gas. But its annual capacity is 20bcm, and that would meet the energy requirements of Iran's Caspian region and enable Tehran to free its own gas production in the southern fields for export. The mutual interest is perfect: Ashgabat gets an assured market next door; northern Iran can consume without fear of winter shortages; Tehran can generate more surplus for exports; Turkmenistan can seek transportation routes to the world market via Iran; and Iran can aspire to take advantage of its excellent geographical location as a hub for the Turkmen exports.

We are witnessing a new pattern of energy cooperation at the regional level that dispenses with Big Oil. Russia traditionally takes the lead. China and Iran follow the example. Russia, Iran and Turkmenistan hold respectively the world's largest, second-largest and fourth-largest gas reserves. And China will be consumer par excellence in this century. The matter is of profound consequence to the US global strategy.
