US's Snow criticises currencies 'on life support'

U.S. Treasury Secretary John Snow implicitly criticised Japan's continued currency market intervention on Monday 8 March after giving a speech.

His comments follow the lead of U.S. Federal Reserve Board Chairman Alan Greenspan.

"No currency can be considered strong if it is propped up on life support with intervention," Snow said in a question-and-answer session after delivering a speech to the National Association of State Treasurers.
