A $17-billion project to build a rail line linking southern Iraq with Europe via Turkey is expected to boost foreign investment in the OPEC nation by nearly 30 percent, an Iraqi deputy was reported on Tuesday as saying. Baqir Al-Saadi, a member of Parliament’s Services Committee, said 10 countries from the Gulf and other regions have so far expressed interest in contributing to “The Development Road” starting from Faw Port and ending at the Turkish border.
