But the countries with the largest export potential, Kazakhstan, Azerbaijan and Turkmenistan, are landlocked. Unlike competitors in other large oil-rich regions such as the Middle East, South America and even Russia, they cannot simply ship their produce by tanker from domestic ports. Instead, these countries must rely on expensive pipelines constructed through foreign territories to reach ports where tankers can load the gas to carry across the world. Many possible routes have been discussed: through Russia, Georgia, China, Afghanistan, Iran and Turkey via Georgia or Armenia, but development of pipeline corridors has been a slow and painstaking process because of the unsettled political climate of the region. And one pipeline route option is through Afghanistan and Pakistan, down to Karachi and western Indian ports. Interested parties in this mega project include neighbours Russia, Turkey, Iran and China, as well as Pakistan and India; and the US, Europe, Japan, Saudi Arabia and even Israel. And every major energy corporation on Planet Earth.
