Exports and imports between Asian countries are the fastest growing sector in international freight, but ports are struggling to cope with the volumes and other logistics infrastructure causes delays and inefficiencies. The average size of ship used in these trades has almost doubled, which means that ports and hinterland logistics are feeling the strain. Some new terminals have opened in Vietnam, but increased capacity would be an advantage. There is strong potential for growth in Indonesia, but again investment in ports is needed. Nhava Sheva, the main container gateway for India, is suffering from severe backlogs because volume of exports are increasing rapidly, whilst Chittagong in Bangladesh has had capacity and labour problems for almost a year.
