Finance Minister Yoshihiko Noda voiced the hope Monday that China's decision to enable the yuan's exchange rate to move more flexibly will turn out to be positive for the global economy.

"I hope it will have a positive impact on the Chinese economy, the Asian economy and the world economy," he told reporters, saying he basically welcomes the decision.

China's central bank said Saturday it has decided to let the yuan's exchange rate move more flexibly, suggesting it may let the currency start appreciating by scrapping its nearly two-year policy of pegging the yuan to the dollar.
