KAMPONG Cham provincial authorities have granted a ferry owner permission to raise and salvage a ferry that sank in the Mekong River more than 30 years ago in order to put it back into service, officials said. “They sent a request letter to me to ask permission because their ferry sank in the Mekong River,” said Kim Dy, the governor of Kampong Siem district. Thut That, governor of Kampong Cham town, said a ferry was lifted from the river last week without any problems, but added: “I don’t know how it can be used again because it is very old.”
