One of Iran's main shipping companies resumed trading with the West this week after six years, but the Islamic country is still far from being reaccepted by the international community, warns an expert. The Azargoun, which belongs to the Islamic Republic of Iran Shipping Lines and can carry 2,500 standard shipping containers, arrived in Hamburg earlier this week. It marked the reopening of the European Container Line between Iran and Europe, which was suspended in 2010 due to sanctions imposed by the U.S. and Europe.

Despite the resumption of trade and shipping following the agreement with Iran over its nuclear program, economic relations between Iran and the West are still far from normal. "We are still pretty far away from full normalization," Torbjorn Soltvedt, head of MENA at risk consultancy Verisk Maplecroft, to CNBC via phone. "What we are seeing is the start of the reintegration of Iran back into the global economy to some extent. But at the same time, you are not really seeing any sort of great influx of investment into Iran yet." Soltvedt said Verisk Maplecroft does not expect a mass influx of investment into Iran in the short term because of risks in the country and the remains of the sanctions regime.
