Noel Choong, who heads the International Maritime Bureau's piracy reporting center in Kuala Lumpur, Malaysia described the Zhenhua 4's rescue by the international naval force.
"Two helicopters arrived at the scene first and helped deter the hijacking. They fired at the pirates, forcing them to flee the ship," he said. There were no injuries during the five-hour ordeal.
"The Chinese ship is very fortunate to have escaped. This is a rare case where pirates have successfully boarded the ship but failed to hijack it," he added.
