well the chinese person interviewed on a doco I saw said the place was too expensive and also there was nobody there so why would he move there
another business person in control of a ship yard said he had no customers but the government forced the bank to give him money to keep building ships

besides I have a mate who has been doing business there for 13 years and been there on and off recreationally for 9 months in the last 11 so clearly I know what I am talking about
