With the outlines of its six idle cranes obscured by thick fog and pouring rain, Kazakhstan's Caspian seaport Aktau seems an unlikely stop on China's much-hyped new silk road. But the sleepy port, which has been badly hit in recent years by new oil routes, is vying for a slice of the pie as competition for Chinese trade warms up on the shores of the world's largest inland sea. China's trillion dollar Belt and Road initiative has been a buzz-phrase in Kazakhstan ever since Chinese leader Xi Jinping unveiled the overland trade and infrastructure vision during a 2013 visit to the capital Astana. For the moment, evidence of Beijing's economic might is light on the ground at Aktau, more than 2,300 kilometres (1,400 miles) from the China-Kazakhstan border crossing that is a key entry point for goods bound for Europe overland.

"This used to be an old port in poor condition with old equipment," said Oraz Koptleuov, a native of Turkmenistan who began working at the port of Aktau as a machinist in 1995.

"Now we have new technology... But there is not enough work. Let there be more work!" he told AFP of the port where 500 people are now employed, down from 700 several years ago. During a recent visit, an AFP correspondent saw a corrugated steel container marked China Shipping being unloaded on an otherwise deserted dock. The container had carried a shipment of engine oil from Turkey to Kazakhstan via Azerbaijan's capital Baku, Koptleuov said, but would make the return journey empty. The experience of the Aktau port mirrors broader economic struggles in energy-rich Kazakhstan, which was badly burned by the oil price collapse in 2014 and hopes a trade and transit boom can ease an unstable commodity dependence. Oil once underpinned business at the port - more than 14 million tons of crude passed through annually - before a more economically efficient network of pipelines grew up, reducing the figure tenfold and triggering layoffs. But port president Abai Turikpenbayev now expects Aktau to emerge as an important overland trade node that can offer an alternative to the better-known northern route to Europe via Kazakhstan and Russia.

"The Chinese call our route the middle route," Turikpenbayev said of the route boosted by Kazakhstan's own investments in domestic road and rail infrastructure. Authorities hope these investments can kickstart stagnating regional economies.

The "middle route" includes a Caspian crossing and allows a shipment of goods from Chengdu in China to reach Istanbul via Aktau in just over 20 days by rail. This is both slower than the northern route, via which trains can reach Vienna in a fortnight, and more expensive than sea journeys that take over a month and account for over 90 percent of East-West trade. Nevertheless, the route via Aktau offers exporters access to very different markets in Turkey, the Caucasus and Iran.
