Treasury Secretary Timothy Geithner on Wednesday said he is quite open to China's suggestion of moving toward a currency system linked to the International Monetary Fund's Strategic Drawing Rights.

Zhou Xiaochuan, China's central bank governor, earlier this month said the world should consider the SDR, a basket of dollars, euros, sterling and yen, as a super-sovereign reserve currency.

Geithner, responding to a question, said he hadn't read Zhou's proposal but added, as I understand it, it's a proposal designed to increase the use of the IMF's Special Drawing Rights. I am actually quite open to that suggestion.

However, he said it should be viewed as an evolutionary building on the current architecture rather than moving us to a global monetary union.
