Mitsui & Co has doubled its spending to about $260m at Singapore-listed Jiangsu Yangzijiang Shipbuilding.

The Japanese trading house is said to have added three more kamsarmax bulkers at China's Jiangsu-based shipyard, bringing to five the number of vessels on order there.

In addition, the Tokyo-listed company has also signed-up for another 180,000-dwt bulker, bringing its capesize order tally to three.
