Chen, speaking at the China High Level Development Forum, said that in the three years from 2005 to 2008, the yuan had appreciated by more than 20 percent while the trade surplus increased.
In 2009, he added, the yuan was steady but the trade surplus fell by 34 percent.
A country's currency appreciation is very limited in helping to rebalance global trade, he said. I personally expect that China could possibly have a trade deficit in March.
