The world’s biggest car maker has halted exports to Iran.As tensions around the Gulf’s most populous country’s nuclear aspirations continue to simmer, Toyota has announced it will halt all vehicle shipments to Iran.Although the statistical impact is likely to be negligible – Toyota only retailed 222 cars in Iran last year – the move is symbolic, showing fraternity with the international trade sentiment against Iran.Though the actual economic impact of Toyota's decision won't even be analytically traceable, the knock-on effect could be potentially huge. As the most powerful Japanese car maker, Toyota's decision could influence other Japanese companies to reconsider their business dealings in Iran. Toyota spokesman Keisuke Kirimoto confirmed the decision. "It is true Toyota has stopped exports of vehicles bound for Iran. We plan to continue to closely monitor this sensitive international situation."Unsurprisingly most of the Toyota sales volume to Iran was driven by demand for Land Cruisers.
