Shanghai-based China United Lines has arrested a container ship it chartered from compatriot Xiamen Shengyunxin Shipping, seeking reimbursement for numerous periods the ship has been off-hire due to its allegedly poor mechanical condition.

The Asian regional liner player had the 2,135-teu containership Hong Chang Sheng (built 1999) seized in Singapore after it was detained for deficiencies following a port-state-control inspection conducted upon its arrival in the city state in March.
