Mr McGowan said the stoush was threatening jobs and investment and hinted at legislation to resolve the deadlock.
"The state government is continuing to explore our legal options regarding Clive Palmer's threat to the more than 3000 West Australians who work on the Sino Iron project,"he said.
"Mr Palmer does not employ anyone on that project.
"He milks more than a million dollars a day cash from the Chinese investors and then attacks Chinese investment. He is a greedy hypocrite."
According to Citic,Mr Palmer has been refusing to release land to the project,over which he holds tenement leases.
Mr Palmer has launched a legal bid to force CITIC to pay $500 million for environmental rehabilitation at the mine site,the latest in a string of legal battles over the project 100 kilometres south-west of Karratha.
