The combined impact of the mining and carbon taxes have reportedly led two large Chinese investors – Shougang International Trade & Engineering and Citic Pacific – to question whether to continue investing in Australia, according to a report by The Australian.

Both groups, which have invested heavily in Australia's resources sector, expressed their concerns at a UBS roadshow in China last week, the report said.

Shougang International Trade & Engineering director Zhu Liangliang reportedly said he was “deterred by evoking tax regime in Australia”, while Citic Pacific project manager Teng Tao reportedly said Citic was “no longer looking in Australia” for assets, the newspaper reported.

Citic's $5.1 billion Sino Iron mine in the Pilbara has been subject to cost overruns and delays, as well as disputes with the mine's primary contractor, among other investments by the company.
