South Korea's plan to sell a stake in Daewoo Shipbuilding to an Australian firm has stalled and other options to lure foreign capital are being considered, officials at Daewoo and its creditors said. Differences over how to value Daewoo's share price and how well qualified the Australian company is to hold a stake in a shipbuilding firm have helped stall the deal, they said. Newcastle, a company formed by Australia-based investors, expressed interest in Daewoo Shipbuilding early in 2000. Officials at Korea Development Bank (KDB), the main creditor of Daewoo Shipbuilding, said the bank's last official contact with Newcastle was in August. "The price the Australian company has in mind appears to be based on the concept that Daewoo Shipbuilding is a bankrupt company," said I.R.
