Vietnam’s de facto decision to ban cruiseships from its ports due to the COVIC-19 coronavirus outbreak has led to further cancellations of cruises scheduled to depart from Singapore.

Norwegian Cruise Line (NCL) is the latest operator to announce that it is cancelling cruises, while Celebrity Cruises is quitting the region entirely.

On Thursday passengers aboard NCL’s 93,600-gt Norwegian Jade (built 2006), while in the middle of a roundtrip cruise from Singapore to Thailand, Cambodia and Vietnam, were informed that their scheduled calls at three Vietnamese ports had been cancelled.
