Barnett to spruik Oakajee to Chinese WEST Australian Premier Colin Barnett will personally lobby Chinese state-owned companies in Beijing to invest in the stalled $5.9 billion Oakajee port and rail iron ore project in the state's midwest. Mr Barnett said cost blowouts in resource projects like CitiPacific's $10bn Sino Iron Pilbara iron ore development, confusion over foreign investment approvals and failed merger bids had created a hestitancy by the Chinese to invest in Australia.
