From a recent Iran Pulse:
The November 24th Interim Nuclear Agreement between Iran and the Six Powers provides for the limited easing of trade restrictions on strategic items such as petrochemicals products, aircraft parts, and precious metals, accounting for up to US$7 billion of trade over the next six months. With the prospect of even wider Iranian trade in the near future, India’s construction of Iran’s first deep-water port to meet modern shipping standards will radically transform Iran’s geo-strategic position, breaking the international economic pressure on Tehran and transforming Iran into the key transit link for the most cost-effective transportation corridor for European-Indian Ocean trade. While Iran and India traditionally have been allies in Afghanistan against Pakistan, New Delhi’s drive to construct a deep-sea port at the Iranian city of Chabahar along with transportation corridors running northward has been motivated by New Delhi’s economic rivalry with Beijing. For Iran, it means a centrally important position in the emerging pattern of trade between Europe and an ascending Asia.
