Cost cutting has helped Sinotrans Shipping to post a significant improvement in its bottom line for the first half of 2018.

The Hong Kong-listed shipowner posted a net profit of $40.3m a more than four-fold increase on the $7.6m achieved a year ago.

Revenue was largely unchanged from a year ago at $497m, but the company was able to show a reduction in costs of over 6% to $449m.
