A Hong Kong company has filed a writ for damages over a failed mine sale in New Zealand.
CKI has filed suit in Melbourne against BlueScope Steel, a company which owns New Zealand Steel.
The case arose out of an attempt by CKI to buy the Taharoa iron sands on the Waikato coast which was blocked by the Overseas Investment Office in 2008.
BlueScope says it will defend itself rigorously and says confidential arbitration is also underway in New Zealand.
No damages figure has been given, but the purchase would have been worth $250 million.
CKI is controlled by a Hong Kong billionaire Li Ka-Shing.
