A Croatian firm had tried to procure a climate test chamber for an Iranian company under UN embargo, a new American government document published on WikiLeaks shows.

Diplomatic correspondence between the American embassy in Berlin and the State Department details an attempt to evade the border controls and break the UN embargo on Iran. A Croatian firm whose name had not been published has been implicated.

In 2008, German authorities asked Americans for information about an Iranian man from Germany, who, through Croatia and Romania, had acquired a climate test chamber for the Iranian Sahig Bageri Group. The Iranian company had been under the UN embargo because of its ballistic missile programs.

Germans knew that the USA was following the "chamber case", the daily Vecernji List writes. Americans said that in 2007 they had warned that the chamber would be sent to Iran with the help of Croatian, Romanian and Russian intermediaries. The scenario included a supposed buyer from Tajikistan. The chamber was to be sent from the United Arab Emirates to Iran on its way to the alleged destination, Tajikistan.

The Americans say that in 2005 they had discussed the intention of the Iranian company Sahig Bagerida to acquire a climate test chamber from a German firm, the name of which is not mentioned in the document. In April 2006, Germany refused the request to allow the exportation of the chamber and warned the manufacturer about its doubts about possible abuse.

In 2007, USA informed the German authorities about a new attempt to evade the control.

"Mid-march we informed them that such a chamber could be sent to Iran through Croatian, Romanian and Russian intermediaries," State Department wrote.

Since the authorities had been alerted of the plan, the Croatian firm placed another offer in a different company’s name, the daily writes.
