Kazakhstan, Central Asia's largest grain producer, plans to increase shipments through Iran by launching a terminal in an Iranian port and building a new railway link, a senior Kazakh official said.

The former Soviet republic shipped one million tons of grain to Iran last year over the Caspian Sea, Asylzhan Mamytbekov, the head of state agricultural company KazAgro, told reporters.

"We will launch a new grain terminal in Iran's Amirabad port shortly," Mamytbekov said. "A storage facility at the Amirabad terminal will be launched in May."

Land-locked Kazakhstan produces over 15 million tonnes of grain a year and exports most of it to Central Asian and Caspian neighbours.

The next step, Mamytbekov said, is to build a new railway link to Iran through Turkmenistan.

"The construction of a railroad connecting (Kazakh) port Aktau with (Iranian city) Gorgan will allow us to increase export capacity to three million tonnes of grain," he said. The link is due to be launched in late 2011.

Kazakhstan harvested 21 million tonnes of grain, mostly wheat, last year and has introduced export shipping subsidies to help producers sell it in a highly competitive market. It has already exported 5.5 million tonnes in the current season. (Reuters)
