Ships could be detained for failing to pay seafarer wages and wider contract failures during a three-month inspection campaign at ports in Europe and Asia.
Two of the 10 port state control regimes, Paris and Tokyo, said a crackdown will begin on 1 September to ensure the rights of seafarers are not being abused.
Seafarers must have seafarer employment agreements that cover wages, paid leave and entitlement to repatriation from an overseas port.
