Treasurer Wayne Swan has exclaimed that he is heading to China for some regular talks with the officials and not for discussing the Government's proposed resource super profits tax.

Mr. Swan told that he was attending G20 finance ministers' meeting in South Korea. He added that he will be visiting China as he is going to be in the region.

He shared that the trip has been planned ahead of the Government's response to the Henry tax review. It also included the clause of 40% tax on mining's super profits.

The Minerals Council of Australia presented KPMG modelling which revealed that Rio Tinto paid an effective tax rate of 35%. This comes out to be the double of 17% which the miners pay.

"This is a mining industry study which has been done using mining industry assumptions and producing mining industry forecast outcomes. So it's entirely predictable," he said.

Mr. Swan added that KPMG had altered the key features of the scheme and he hasn't seen the details, so far. The Government was comfortable releasing the unpublished data regarding the mining tax, he added.

He expressed his disappointment over the standard of debate over the tax. However, the Government is open to all kinds of negotiations, he said.
