The first international container ships began arriving in Iran this week after the nuclear deal between Tehran and world powers, yet many ship owners remain wary of resuming business until sanctions are removed - still some months away. Iran had depended on foreign ships for much of its imports, but has relied more on land routes and its own commercial fleet, particularly since 2012, as layers of sanctions led to an exodus of Western shipping firms, leading to supply disruptions. In one of the first signs of change, the world's third largest container shipping group, France's CMA CGM, said on Monday it would restart services to Iran in early August.
