The world's biggest tanker owner, Cosco Shipping Energy Transportation (CSET), has posted lower profit for the first quarter.

The CoscoCS-controlled company said net earnings were CNY 563.11m ($81.65m), compared to CNY 546.34m in 2016.

Revenue was lower at CNY 2.66bn, from CNY 4.35bn the year before.

It said the smaller figures were due to the reorganisation of the company last year after Cosco and China Shipping merged.
