In July 2008, the German Federal Office for Economics and Export Control (BAFA) concluded its year-long investigation into German engineering firm Steiner-Prematechnik-Gastec's plans to build equipment for three Iranian liquefied natural gas plants, according to The Jerusalem Post. A German government spokesman stated, "Because the equipment would be built here and then sent to Iran that work does not fall under any existing sanctions involving Iran." However, The Jerusalem Post later reported that the deal created tension between the German and Israeli governments.
SPG's website lists a sales office based in Iran, SPG Persia.
