Few have noticed a crucial meeting that took place during the recent Non-Aligned Movement (NAM) summit in Tehran, between senior Foreign Ministry diplomats from Afghanistan, India and Iran. Their ultimate goal; a new Southern Silk Road connecting Iran to Central and South Asia through roads, railways and last but not least, major ports.
The crucial Silk Road port in this case is Chabahar, in Sistan-Balochistan province in southeast Iran. Tehran has already invested $340 million to complete 70 per cent of the port construction - a decade-long project.
But with US and EU sanctions biting harder and harder, Tehran expects Delhi to come up with a closing $100 million. India has already invested $136 million to link Chabahar to Afghanistan's ring road system.
One does not have to be Alexander the Great to notice the fastest connection between Kabul and India would be through the fabled Khyber Pass. But that does not take into account the accumulated historical venom between Islamabad and Delhi - their constant promises to increase cross-border trade notwithstanding.
With Chabahar linking Iran directly to Afghanistan and India, in theory Pakistan is sidelined. But it's much more complicated than that.
According to National Iranian Gas Company (NIGC) managing director, Javad Oji, the stretch from Iranshahr in southeast Iran to Zahedan and the Pakistani border is 90 per cent ready. The 900 kilometre-long pipeline on the Iranian side should be active one year from now. It's up to Islamabad to finish its stretch.
Totally in character in terms of interminable Pipelineistan soap operas, IP used to be IPI (Iran-Pakistan-India) - but Delhi pulled out, forced by relentless pressure from the Bush and Obama administrations.
And it's here that the going gets really tough - because there's nothing Beijing would love more than turn the former IPI into IPC.
And then, moving ever eastward on the great Grid, there's Turkmenistan, lodged deep in Central Asia, which, unlike Iran, you may never have heard a thing about. Let's correct that now.
Gurbanguly Is the Man
Alas, the sun-king of Turkmenistan, the wily, wacky Saparmurat "Turkmenbashi" Nyazov, "the father of all Turkmen" (descendants of a formidable race of nomadic horseback warriors who used to attack Silk Road caravans) is now dead. But far from forgotten.
The Chinese were huge fans of the Turkmenbashi. And the joy was mutual. One key reason the Central Asians love to do business with China is that the Middle Kingdom, unlike both Russia and the United States, carries little modern imperial baggage. And of course, China will never carp about human rights or foment a color-coded revolution of any sort.
The Chinese are already moving to successfully lobby the new Turkmen president, the spectacularly named Gurbanguly Berdymukhamedov, to speed up the construction of the Mother of All Pipelines. This Turkmen-Kazakh-China Pipelineistan corridor from eastern Turkmenistan to China's Guangdong province will be the longest and most expensive pipeline in the world, 7,000 kilometers of steel pipe at a staggering cost of $26 billion.
