US Treasury Secretary Timothy Geithner said Wednesday that China was playing a "very important" role in containing the current financial crisis that has slammed the brakes on global growth.

"I think China is playing a very important stabilizing role in this financial crisis we're seeing globally," he said in an interview with financial network CNBC.

He also said that the United States was working closely with China to ease financial turmoil as the world's most populous nation implemented its own measures to stimulate economic growth.

"The things they are doing to get their economy stronger, to encourage domestic demand growth, to allow further evolution in their basic financial framework, those things are very important policies and we're working very, very closely with them," Geithner said.

"I think they have a lot of confidence in the policies we're pursuing," he added.
