PARIS: IMF chief Dominique Strauss-Kahn has said a discussion over China's call for a new world currency is "absolutely legitimate" and is likely to take place in coming months.

Strauss-Kahn also said such a debate is "interesting" but isn't likely to move quickly.

He told reporters in Paris on Wednesday that he didn't believe the dominance of the US dollar among currencies was over, adding: "Even the Chinese don't believe this."
