Canada says yuan needs to rise to help imbalances

OTTAWA, Nov 20 (Reuters) - The Canadian government reiterated a call on Thursday, ahead of this weekend's Asia-Pacific summit, for the revaluation of exchange rates of key Asian countries including China.

A senior government official, briefing reporters on the upcoming summit, said a number of world leaders had raised concerns over global imbalances and said exchange rates were one of the factors.

He said rates would "need to move in appropriate directions". (Reporting by Randall Palmer; Editing by Peter Galloway)
